I don't know about handling the Packer's offense but the Bears defense played the Packers about as well as any other NFL team.
Obviously, you'd like to see Paea be productive but Melton is the guy that really needs to establish himself now that Harris is gone. And they really need a 3rd DE work into the rotation as Peppers and Idonijie faded over the last month. Is Corey Wooten that guy?
Tim Jennings came out of nowhere and was really solid all year, but he struggled in games against the Pack. Bowman has the athletic ability to play the LCB, but can he do the dirty work and take the job from Jennings?
I'd like to see what Joshua Moore can do too - hopefully he's been working on that anemic bench press.
