USC tight end Xavier Grimble appears set at tight end. Because of Grimble's size last year (265 pounds), there were rumbles about him ending up on the offensive line. Grimble has done a good job controlling his weight and is consistently in the 245-pound range.
Grimble's playing time will depend on how much Rhett Ellison plays and how effective he is. Grimble, though, is a big target and could push his way into the lineup, particularly if they go with two tight end sets.
