I understand that, but we're one knee injury away to Bell or Chandler from a real disaster.
We still have cuts yet to happen. The team seems to have a knack for picking up a veteran guy after cuts to fill a position of need. We have done it at least the past 2 seasons and it has worked out pretty well (Dwan Edwards, Quintin Mikell)
Keeping 6 defensive ends is unusual for sure, but the team is in an unusual position with the DE position next year. Hardy could be gone, Johnson is getting paid extravagantly, and Alexander will be a RFA. That leaves too many question marks to be unprepared for.
I only believe that Horton is getting reps with the first and second team defense because they know Alexander will be out and this is going to thrust Horton into a bigger role. They want him to be prepared.
