4. Mitch Unrein, DE, 81.9
What can you say about Mitch Unrein? All he does is go out there and reward the Bears with steady play. The Bears have brought in multiple guys to replace Unrein including Jonathan Bullard and Jaye Howard but Unrein continuously keeps them on the bench and himself on the field.
Unrein isn’t flashy and doesn’t make a lot of big plays, but he does his job and makes things more difficult for offenses to operate. Those are the types of players that PFF loves, and it’s reflected here in his rating. Unrein is a bit of a surprise, but certainly not a shock.
