The flag on Shack was bizarre as well. No block in the back, no clip, no targeting, and the whistle hadn't blown. Shack got a good hit on the kid who didn't see it coming, but because the kid got hurt on the play that's a flag? The hold on Wheeler was ridiculous as well. It was at the LOS and not exactly impacting the play whatsoever. Kind of amazing that the KSU O-line was so excellent and never held the entire game. Bravo Big 12 refs.
