AJ Wentland embracing a new football culture with IBM Big Blue in Japan

After building one of the most decorated careers of any American defender in European football, linebacker AJ Wentland has taken on an entirely new challenge. The former Wroclaw Panthers standout is now anchoring the defense for IBM Big Blue in Japan’s X League Premier, helping transform a team that struggled defensively a year ago into one of the league’s early success stories.

The 31-year-old from Rockford, Illinois arrived in Japan following three outstanding seasons with the Panthers, where he averaged 13 tackles a game and led the European League of Football with 144 tackles in 2025. His European résumé also includes championships with the Swarco Raiders Tirol, the Dresden Monarchs, and the Kuopio Steelers. Now, after helping IBM Big Blue to two wins in its first three games, Wentland sat down with American Football International to discuss his new adventure.

A fresh opportunity

For Wentland, the move to Japan was about timing as much as ambition.

“I have always heard good things about playing in the Japanese X League,” he said. “With the turbulence of the leagues in Europe this year, when I had the opportunity to go to Japan it just felt like the perfect opportunity to go for it.”

The opportunity came after IBM Big Blue head coach Mike Phair reached out. From there, the process moved quickly, with the organization conducting interviews with players, coaches and management before offering Wentland the chance to join the club.

“The Wroclaw Panthers were also very helpful in the transition process and were very supportive of me going for this next opportunity in my career,” he explained.

A different brand of football

Although American football is played under the same rules around the world, Wentland has quickly discovered that the style in Japan differs from what he experienced across Europe.

“The players are very technical, athletic and quick,” he said. “They are very cerebral and understand the game on a deep level. Offenses enjoy running a lot of perimeter and quick game.”

By comparison, he sees a more physical style across the European game.

“In Europe the players are bigger and more physical with offenses running a mix of pro-style and spread offenses. Both are very good, but I have been very impressed with the Japanese speed and endurance.”

Another difference is roster construction.

“In Japan teams only have four professional import players, whereas in Europe teams have upwards of 10-14 foreign players. The Japanese take football very seriously and they each treat the game like a professional.”

Building a defensive identity

The early returns have been encouraging. IBM Big Blue has opened the season 2-1 after defeating two playoff-caliber opponents, and Wentland believes the team’s identity is beginning to take shape.

“We feel good after that second win against the Challengers,” he said. “We have beaten two very good playoff-caliber teams in the first part of the season. We feel like we certainly should have and could have beaten Minerva in Week 1.”

Wentland recorded 10 tackles in the victory over the Challengers, but he’s more interested in what the defense has accomplished collectively.

“Our defense is currently averaging 13 points per game with eight takeaways. We have blocked field goals and punts, and I just think we have a really gritty group of guys who have bought in to what we want to be here at IBM.”

That mindset is reflected in the team’s motto.

“We have a blue-collar mindset on this team and our motto is GRIT. We believe in getting better every day.”

More than football

The X League’s unique schedule has also required an adjustment. Games stretch from May through late November, with a lengthy summer break before the regular season resumes on August 30.

“The current summer break is a good time to go home and visit the family,” Wentland said. “I’m currently back home in Rockford, Illinois, training and spending time with my family. Recovery, training and game planning become very important.”

Away from football, Wentland says living in Japan has been every bit as rewarding as playing there.

“Japan has been a transformative experience,” he said. “Just seeing how these guys approach work every day and how they embrace the leadership and mentality to be great has been incredible. The organization is so well run, and everyone works tirelessly to help the team succeed.”

For a player who has already enjoyed championship success across Europe, the latest chapter has offered something different.

“Japan’s culture is amazing,” Wentland said. “It’s the safest, cleanest and most respectful country that I have lived in by far. Amazing food, beautiful nature. All in all, it’s been an incredible experience so far.”
