Making the rounds at Super Bowl XLIX, Allen told the NFL Network he expects the Bears to be a more disciplined team under Fox.
"You look at what coach Fox has done over the history of his career," Allen said. "I think we'll be very disciplined. We'll be very cohesive. With Fangio coming in, you've got a big 3-4 background. Fox ran a 4-3 his whole life. So I think we're very versatile in how we can use our players. I'm excited to see what the plan going forward is."
It's unknown how Allen might fit in Chicago's new defensive scheme in 2015, but the new coaching staff shouldn't have trouble finding ways to best utilize the five-time Pro Bowler's pass-rushing skills. While most signs point to the Bears shifting to a 3-4 front, there's a chance the club could show some hybrid looks in 2015, as it's uncertain how quickly the personnel department can totally turn over the roster to fit the scheme.
In the past, Allen seemed reluctant to move from defensive end in a 4-3 front to outside linebacker in a 3-4.
"I want to end my career as a defensive end. And I'm not playing a 2-gap, let me just throw that out the window now," Allen said just before the 2012 season when there was talk of the Vikings changing schemes.
Allen, who will be 33 in April, seems more amenable now to a switch and said Fox will inherit a hard-working group on defense.
"One thing we do is we work. I'll be honest, I don't think we had a bad practice all year," Allen said. "Now it didn't always equate to wins and victories. We came up short. I think he's going to inherit guys that are eager, that want to win. That's one thing that was very prevalent in our locker room: guys wanting to win. I think coach Fox is going to give us that direction and give us that attitude, that sense of focus, purpose and discipline to get to where we want need to get."
Allen accepted the Salute to Service Award on Saturday during the "4th Annual NFL Honors" awards show in Arizona, and received the award in recognition of his efforts off the field. Through his Homes for Wounded Warriors Foundation, Allen helps to provide financial assistance to aid in making homes more accessible for veterans returning from war with debilitating injuries.
Allen created the foundation in 2009.
