Brown is going to push for the 53. Ivie and Carrell for the PS.
With Irving and Moore facing suspensions, I could see Ivie being kept if he shows anything.
I have Lawrence, Crawford, Charlton, Mayowa, Tapper at end, and Collins, Thornton and Paea at tackle. That gives us eight linemen with Irving and Moore out. I had us carrying nine or 10, so I think Ivie could end up as a placeholder. However, he might have to beat out Neal for that spot ... although we could carry both.
Here's how I see the defensive depth on the 53 after the first week of practice:
DE (6) Tyrone Crawford, DeMarcus Lawrence, Taco Charlton, Benson Mayowa, Charles Tapper, Lewis Neal
DT (4) Maliek Collins, Cedric Thornton, Stephen Paea, Joey Ivie (Crawford and Neal can also play tackle)
LB (7) Sean Lee, Anthony Hitchens, Jaylon Smith, Justin Durant, Mark Nzeocha, Kyle Wilber
CB (5) Orlando Scandrick, Anthony Brown, Chidobe Awusie, Jourdan Lewis, Marquez White
S (4) Byron Jones, Jeff Heath, Xavier Woods, Kavon Frazier
Suspended: David Irving, Damontre Moore, Damien Wilson, Nolan Carroll
Without the suspensions, Ivie would definitely just be a PS contender. John Lotulelei, Lenny Jones and Robert Blanton are possibilities to take his or one of the other spots.
