There are some players that the Rams are going to have to make some tough decisions about. Here is my list of players that will no longer be with the team next season for cap reasons.
Whitworth.......... his performance is on a down trend and his cost is just too high
Brockers........... he isn't worth $11 mil
Fowler............... good performer but not great. However will get elite money in the FA market. Rams can't afford him, and shouldn't pay him that kind of money.
Since Blythe will be a FA, I doubt he'll be back as well.
I know Littleton will be a FA; I think they'll try hard to keep him as he is a consistently good performer who seems to get better every year. Sure tackler, really good cover ILB. Playmaker, even on STs. The kind of guy you keep.
