We aren't going to keep more than 4 safeties.
Roy as a starter, Davis as an incumbent/fantastic ST player are pretty entrenched.
Next we have Watkins, who, if he lives up to the name he's created and the fact that he's a rookie, will probably stay.
It is then between Bariault, Coleman and Pile. Pile most likely leaves as he has little value on ST and isn't a good starter.
Between Bariault and Coleman, I think it depends on if we can start Watkins. If we can go with watkins, we probably cut Coleman and keep 3 SS's and 1 FS (watkins). If Watkins can't start, we probably keep the experienced Coleman and get rid of Bariault (regardless of what Parcells said - he said that about Daleroy Stewart, Willie Blade, etc.)
