Someone on here made a point that we really will not have a ton of open roster spots for DE. It's easy to say we need to add 2-3 pass rushing defensive ends but who do you cut for them?
You don't have to cut anyone right now., and once you get to training camp, you just let things get sorted out.
Right now, we have DeMarcus Lawrence, Benson Mayowa, and Charles Tapper at DE. Maliek Collins and Cedric Thornton are at DT. Tyrone Crawford and David Irving can play both.
That's seven players.
Rod Marinelli prefers to dress eight DL for games in order to have a quality rotation. Ideally, I'd like to keep 10 DL on the 53 man roster and 2-3 more on the practice squad.
There will be multiple factors at play when the initial cut to 53 takes place next September, but there is definitely room to add 3 more DL.
Terrell McClain (29 July), Jack Crawford (29 Sept) and Ryan Davis (28 Feb) are all set to become unrestricted free agents.
McClain's a good player, but Dallas opted to pay Cedric Thornton instead of him last year and he will probably find more money elsewhere. It would be better to add another young DT to the unit instead.
Crawford's a solid utility player without a true home position. I would look to spend some money on a true veteran DE to take his spot.
Davis' spot can go to a draft pick.
RDE: Benson Mayowa, veteran FA, possible rookie
NT: Cedric Thornton, possible rookie
UT: Maliek Collins, Tyrone Crawford (can play together in Nickel a lot)
LDE: DeMarcus Lawrence, David Irving, Charles Tapper
Jason Garrett is big on competition and adding three more legit DL would allow for a lot of it. Starters would be worried about losing snaps to the back-ups and those guys would be fighting with each other every week in order to dress for the game.
