His regression this past season was odd. Up until this season, he was a force who made the entire DL better (when he played). He was more available than ever this season, but looked like he'd lost about fifteen steps and didn't make anyone around him better.
My thoughts as well. He was always very productive when on the field....but was never healthy. Then, in a contract year, he's healthy buy totally was ineffective. Maybe losing a digit was a big deal.
