Mack's inclusion here might be ironic, given that Chicago acquired him from Oakland via a trade last September. And it's not like he single-handedly put the Bears back in the playoffs. The defense has a lot of great parts, with valuable players on all three levels, like Akiem Hicks up front and Eddie Jackson in the back end. But Mack (47 tackles, 12.5 sacks, one pick, six forced fumbles in 14 games) is the face of the unit right now. Yeah, OK, so this organization recently let Matt Forte and Devin Hester play for other squads -- but it's hard to imagine the Bears ever letting Mack go. Or at least, I don't want to imagine it. (I'm still emotionally affected by the way those guys went out -- I realize that both partings were probably the right football decisions, but I still hate the fact that I can find images of Forte in a Jets uniform and Hester as a Falcon. I just don't want to do it.)
