Brian Allen would be the first one to tell you that there are some notable differences between he and his older brother, Michigan State rising junior guard Jack Allen.

The mere fact that Brian Allen would tell you that is the first difference.

"Yeah, you picked out one of the differences, he (Jack) is kind of a shy guy,'' said Brian Allen, a 6-foot-2, 285-pound Class of 2014 commit and the defending heavyweight wrestling champion in his Illinois school classification.

"Jack doesn't like to talk football when he's not playing. He likes to lay low. I'm a little more outgoing.''

But no less fierce.

Allen impressed teammates during practice at the prestigious U.S. Army All-American All-Star Bowl in San Antonio, Texas, so much that he was selected as a captain for the Jan. 4 high school all-star game.

Allen played left tackle this past season at Hinsdale Central High School in Hinsdale, Ill., but he'll likely be moved inside to guard.

"I had to play left tackle because of the depth we had,'' Allen said. "It was the first time I'd played the position, and it was hard to get used to. I don't think I'll find myself in that position again because of my height, but it probably helped my out with my footwork.''

Allen is currently focused on his wrestling season, as he aims to defend his Class AAA state title.

"I'm doing well so far in wrestling so far,'' said Allen, who was 48-0 last season. "I'd say the wrestling practices are a lot more conditioning than football, you're never really standing around. In football, you're on for 8-to-11 seconds, and then off 30 seconds. In wrestling, there aren't really many breaks.''
