The Oakland Raiders took some extreme measures to prove that JaMarcus Russell wasn't doing everything in his power to be a good NFL player.
Appearing on New York's WFAN (h/t Andrew Marchand of the New York Post), former offensive lineman David Diehl said Raiders coaches used to give Russell blank tapes to determine if he was studying film.
Diehl noted Russell would come into the Raiders' facilities the day after receiving the tapes saying that he watched the blitz packages.
Who would have known that Russell wasn't fully dedicated to being an NFL quarterback?
