Broaddus seemed to be making light of this on Break today, suggesting that it's a curious thing to expect a rookie to get snaps this late in the season.
I agree with BB sometimes, and don't sometimes, and on this, I don't.
No one is ignorant that we could stand to be stronger in the run game. Fehoko was drafted under the theory that he's a DE who has Tyrone Crawford and/or Michael Bennett traits... able to make contributions whether playing outside or inside.
Why wouldn't you want to have a chance to assess what he can do in this last game if the opportunity were to present itself?
