With spring practice now in the books, here's another educated guess at OU's current depth chart. Not much movement on the offensive side of the ball, but I did some shuffling on defense.
Note that in the parlance of the 3-4 defense, the Sooners' appear to be using Eric Striker in more of the JACK role with Geneo Grissom playing the SAM. Don't get too hung up on trying to fit their responsibilities into the traditional definitions of the positions, though, because I suspect the Stoops brothers have their own plans for how they intend to use them.
Hit me up in the comments with any feedback.
