Mahnen’s Fearless NFL Week 5 Predictions: When bookmakers, passports and bad math collide

Week 4 produced a 9-7 record, the first winning week of this exercise and enough evidence for the model to demand a contract extension. The season total is 28-36. The coin toss is still ahead, but it has stopped taking my calls in public.

Week 5 adds the International Bookmaker Adjustment. William Hill inspired the idea, because any bookmaker with a British passport deserves a place in this formula. Favorites receive extra weight, and the larger the spread, the heavier the thumb. This is basically borrowing somebody else’s homework and adding flags.

The painful Week 4 review

The formula correctly selected the Giants, Bears, Packers, Ravens, Vikings, Chiefs, Seahawks, 49ers and Falcons. The Giants won 36-24, validating the Jameis Winston World Cup coefficient and several other conclusions that no responsible statistician would draw from one afternoon.

The seven misses included Pittsburgh losing to Cleveland, Washington losing 30-13 in London, Buffalo surrendering 29 points to New England and Detroit falling at Carolina. Houston and Philadelphia also lost close games after receiving confident endorsements. Confidence remains the leading indicator of trouble in this column.

A 9-7 week is progress. It is also the sort of record that can make a forecaster forget the 19-29 hole dug during the first three weeks. Fortunately, readers have excellent memories and the internet has screenshots.

Week 5 predictions

Tampa Bay Buccaneers at Dallas Cowboys

Tampa Bay brings Belize-born Rakeem Nunez-Roches and German tackle Paul Rubelt. Dallas counters with Jamaican and Nigerian practice-squad connections and a global brand that has been crossing borders since long before anyone invented an international player pathway.

The football factor is Tampa Bay’s quarterback situation. Rookie Jalon Daniels is making his second start on a short week and on the road, while Dallas just scored 34 points in Houston. The market makes the Cowboys an 8.5-point favorite, which is less a thumb than a full forearm.

Pick: Dallas Cowboys

Philadelphia Eagles at Jacksonville Jaguars

London gets the week’s most international game. Philadelphia opened with six players tied to Australia, Cameroon, Kenya, Nigeria and Zimbabwe. Jacksonville had three, but the Jaguars have enough London experience to know where the good coffee is and which way to look before crossing the street.

The football factor is Jacksonville’s defense after holding Cincinnati to 17 points. Philadelphia has lost two straight and now travels after Lane Johnson’s retirement. The Jaguars are favored by 7.5, so the International Bookmaker Adjustment overrules Philadelphia’s larger passport stack.

Pick: Jacksonville Jaguars

Cleveland Browns at New York Jets

Cleveland’s season-opening roster reference contained no qualifying international player. The Jets had six connections across American Samoa, Lesotho and Nigeria. On the international spreadsheet, this matchup begins 6-0 before either offense gets a chance to make it uglier.

The football factor is a game total of only 39.5, which suggests that every first down may require a permit. Cleveland beat Pittsburgh last week, but the Jets are a 2.5-point home favorite and hold the decisive international advantage. In a game built for field position, the market gets the tie-breaking vote.

Pick: New York Jets

Chicago Bears at Green Bay Packers

Chicago’s international group reaches American Samoa, Australia, Brazil, Canada and South Africa. Green Bay answers with Australia, Canada, Germany and Ireland. The Packers have the geographic charm; the Bears have the head count and Brazilian kicker Cairo Santos.

The football factor is Chicago’s defense and control of the clock. The Bears held the Jets to 12 points and improved to 3-1, while Green Bay needed all afternoon to escape winless Tampa Bay 17-14. Chicago is favored by 2.5, and this time the market and the secret formula have signed the same treaty.

Pick: Chicago Bears

Cincinnati Bengals at Miami Dolphins

Miami owns the international edge with connections to American Samoa, Cameroon, Canada, Nigeria and England, plus commercial rights across Latin America and Spain. Cincinnati counters with Canadian running back Chase Brown and Japan-born receiver Andrei Iosivas.

The football factor is whether Miami can score enough to turn its international advantage into points. The Dolphins managed 10 in Minnesota, while Cincinnati still has Joe Burrow and Ja’Marr Chase after a disappointing home loss. The Bengals are favored by 7.5, and the bookmaker’s thumb is sitting directly on the passport column.

Pick: Cincinnati Bengals

Las Vegas Raiders at New England Patriots

Las Vegas opened with players connected to Canada, Guinea and Japan and markets stretching from Mexico to the United Arab Emirates. New England’s roster links were Australia and Germany. The Raiders win the atlas portion comfortably.

The football factor is New England’s offensive variety. The Patriots used motion on more than three quarters of their plays in the 29-26 win at Buffalo, their highest rate in years. Las Vegas pushed Kansas City to the final minutes, but New England is favored by 3.5 and has the fresher statement win.

Pick: New England Patriots

Minnesota Vikings at New Orleans Saints

New Orleans brings Canadian, Jamaican and Northern Irish roster connections and adds France and Italy to its international markets. Minnesota’s principal player link is Australian punter Brett Thorson. The Saints win the flags and the Italian bonus without needing a recount.

The football factor is Minnesota’s defense. The Vikings are 4-0 despite an offense that has occasionally treated touchdowns as an optional upgrade. They are favored by only 1.5, but a team that keeps winning ugly deserves respect from a formula specifically designed to look ugly.

Pick: Minnesota Vikings

Houston Texans at Tennessee Titans

Houston’s international group includes Italian tackle Max Pircher, Germany-born tight end Marlin Klein and Jamaica-born pass rusher Danielle Hunter. Tennessee counters with Canadian receiver Elic Ayomanor and Samoa-born Laki Tasi. Houston takes the count and the Italian-name bonus.

The football factor is Houston’s pass rush against an offense that scored seven points against the Giants and 18 against Baltimore. The Texans are favored by 7.5 even after losing to Dallas, a clear message that the market has not been hypnotized by Tennessee’s six-point improvement.

Pick: Houston Texans

New York Giants at Washington Commanders

The Giants opened with six international connections across American Samoa, Australia, Canada, Nigeria and England. Washington had five, reaching American Samoa, Gabon, Germany, Haiti and Trinidad and Tobago. This is close enough for the Winston World Cup clause to request an extension.

The football factor is last week’s film. New York scored 36 against Arizona, while Washington managed 13 in London. The Commanders are favored by 3.5, making this the one place where I politely remove the bookmaker’s thumb and replace it with Jameis Winston waving a Dutch flag. Diplomatic immunity remains undefeated.

Pick: New York Giants

Indianapolis Colts at Pittsburgh Steelers

Indianapolis has Austrian tackle Bernhard Raimann and Nigeria-born Roy Mbaeteka. Pittsburgh answers with Australian punter Cameron Johnston and German linebacker Julius Welschof. The international score is level, so the model has been forced to examine football.

The football factor is Pittsburgh at home after a divisional loss. Indianapolis was excellent in the 30-13 win over Washington, but the Steelers are favored by 2.5 and have the defensive structure to make the Colts earn every drive. This is not a comfortable pick, which makes it perfectly at home here.

Pick: Pittsburgh Steelers

Denver Broncos at Los Angeles Chargers

The Chargers opened with seven international players connected to Australia, Canada, Germany, Haiti and Hong Kong. Denver had three with links to Australia, Jamaica and Nigeria. The secret formula wants the Chargers by a landslide and has submitted a formal complaint.

The football factor is Los Angeles starting 0-4 while repeatedly giving opponents short fields and extra chances. Denver is favored by 3.5 despite its own uneven offense. The market receives additional weight this week, which is unfortunate news for the team with the better airport connections.

Pick: Denver Broncos

Detroit Lions at Arizona Cardinals

Detroit’s wider international group reaches American Samoa, Egypt, Nigeria, Canada and Tonga. Arizona counters with Austria, Canada and Denmark. Detroit wins the player count, although Danish center Hjalte Froholdt remains one of the best names in the entire weighting system.

The football factor is scoring capacity in a game carrying a 54.5 total, the highest on Sunday’s board. Both teams allowed more than 30 last week, so the safer choice is the offense the market trusts more. Detroit is favored by 5.5 and gets the full bookmaker boost.

Pick: Detroit Lions

San Francisco 49ers at Seattle Seahawks

San Francisco brings roster connections to Belgium, Canada, Liberia and Mexico. Seattle counters with Australia, New Zealand and Puerto Rico and one of the league’s broadest commercial maps. The 49ers lead the passport count; the Seahawks win the export department.

The football factor is Seattle’s home field against a division rival. San Francisco is unbeaten and has the stronger recent offensive film, but the Seahawks are favored by three after handling the Chargers. This is where a bookmaker-weighted system earns its name and makes me nervous at the same time.

Pick: Seattle Seahawks

Baltimore Ravens at Atlanta Falcons

Baltimore opened with players born in Canada, Greece, Panama and England. Atlanta’s group reaches Canada and Nigeria. The Ravens own the international roster edge, while the Falcons counter with the universal language of scoring 45 points in New Orleans.

The football factor is Atlanta’s offensive surge. Michael Penix Jr. and the Falcons finally turned their skill talent into touchdowns, while Baltimore needed a tight finish to put away Tennessee. Atlanta is now favored by 3.5, and the market move gets more weight than Baltimore’s passport advantage.

Pick: Atlanta Falcons

Buffalo Bills at Los Angeles Rams

Buffalo’s international group includes two Canadians and an English developmental lineman. The Rams answer with Australia, two Canadians and Zimbabwe, backed by seven international marketing territories. Los Angeles wins both the count and the brochure.

The football factor is the Rams’ response after their Denver collapse. They went to Philadelphia and won 24-20, while Buffalo followed a turnover-heavy win by losing at home to New England. The Rams are favored by three in the week’s other 54.5-point game, and the international market adjustment closes the argument.

Pick: Los Angeles Rams

Final warning

These predictions are not betting advice, financial advice or proof that a British bookmaker can repair an American forecast. There are easier ways to lose money than using my picks, including buying stadium beer, accepting an airport exchange rate or trying to win it back with one more souvenir. Use this column only to ridicule its author. William Hill may be international; the losses remain entirely local.
