How often have you seen those Oklahoma drill standouts have a lot of success on the field? In my experience it's not a guarantee or something seen consistently.
In my view, with the limitations on practice times, it's a waste of time. (If Bama did these drills I'd say stop and use the time for live kicking.)
(I'll never forget seeing fRan use those drills when he was trying to "warm up" to the fans. It was hollow...so orchestrated and meant nothing. DuBose included there ... Shonta Ray was a hell of a warrior in Oklahoma drills but good lord he certainly lacked the acumen for football.)
