He didn't play DE last year, even after Ott injury, so don't see it happening this year. He will be needed as third DT and think he will get plenty of time there along with goal line and short yardage aituations
I think they've tried him at DE and he is better suited inside. Maybe he could be a DE in a goal line package when they need a little more beef or a 3 DT look.
Last year, the Iowa defense wore down in the month of November, and so Faith plays an important role to get more guys in the rotation and on the field. They need his depth at DT and he's a heck of a 3DT.
