5. Danny Trevathan, ILB, 47.0
This one is disappointing to see and also shows how sometimes PFF grades can be puzzling. Trevathan, of course, was Ryan Pace’s prized off season acquisition and played well in week one scoring an 80.1 average from PFF.
There’s no question that Trevathan’s performance in week two was poor. He missed a couple tackles and was out of position a few times in pass coverage. Whether Trevathan’s performance was bad enough to drop his season grade 33 points is a little bit of a head-scratcher.
To make matters worse, Trevathan will now be sidelined multiple weeks because of thumb surgery. The Bears will hope he can get back as quickly as possible and get him back on the field because he will desperately be needed to take this defense to the next level.
