I never rushed the passer when I played, but I've been told/read that is all about rhythm and setting a guy up for counter moves. All the greats played every down. They just showed a graphic of Matthews yesterday and he was on the field for 60 some plays last week. Porter, Debo, Lloyd, Woodley, Greene... they rarely came off the field.
If JJ can't play 45+ snaps and be effective, he better work more on his conditioning. Let's be honest.
I agree about Dupree being broken in slowly, but JJ is in his third year. He should have the majority of the snaps with Debo giving him a blow for 2-3 series tops. They need to see if JJ can be a good player or if he is just a body out there. Playing 20-25 snaps a game is purposely holding him back and delaying his development if he has the talent to play in this league.
