losing Jirehl railroaded last season, so yes losing all those guys would railroad this season.
It would hurt depth, but my expectations wouldn't change much.
Brock was a loss last year, but if Norton had stayed healthy would Norton be the guy we are talking about going into this season.
For me our running game will be solid if our OL is solid.
QB is a big concern, just because going into a season with an inexperienced QB is a roll-of-the-dice. Last year is proof.
With OL/TE positions, unless it is an all conference player, IMO it's next man in!
On defense, I feel Heacock and staff have a lot of quality players at all 3 levels. My biggest concern on loosing guys would be the CB position.
This hurts from a depth standpoint if we suffer a rash of injuries.
