Here's a look at each of Oklahoma's seniors (doesn't include Prentice McKinney, who is injured and has a redshirt year available):
Jonathan Alvarez, OL
Alvarez started 16 games during his career at center and guard but injuries ended his senior season prematurely.
Rodney Anderson, RB
Anderson is not a senior but recently declared for the NFL Draft after suffering a season-ending knee injury in September. Anderson rushed for 1,161 yards and 13 touchdowns last year.
Nick Basquine, WR
The former walk-on from Norman North has 24 catches for 320 yards and two touchdowns during his career at OU.
