On the field he more closely approximates what Stafford can do plus has the added dimension of being able to run the ball which gives him value even when Stafford is 100%. Now I have no idea where he would rate on the Buccaneers Baker @#$%& scale but Wentz looked like a poor man's Stafford with more running ability. JG is the epitome of a vet back up, good for spot cleanup work and another guy in t he QB room that might have something to say but that is it. Way better than previous Rams backups sans "Wentz but nothing to be excited about either.
