Why not? IMO Anderson at 35 is there for brains. Pro game prep: Film study, reading defensive alignments, pre snap adjustments/ protections and audibles, and as an emergency QB.
Foles can win games. His current contract puts him in the neighborhood between Mayfield, McCown, Tyrod and Dalton.
If Allen flames out over the next few games, and the D/ ST are playing well it holds the locker room together.
Ivory and Murphy aren't McCoy, but they are capable RBs.
