I wish I knew. I just watched every important call go in favor of Alabama today. I do not understand how Bama gets every call, and Florida does not. Heck, Florida's Will Grier, if we believe him, obtained supplements over the counter. In 2013, the Alabama football team was caught using deer antler spray (also illegal), which they obtained in a hotel room, and got away with it!
Something is fishy in Tuscaloosa with regards to referees, refereeing, performance enhancing drugs, and recruiting, but anyone not in Tuscaloosa will just write the accusations off as complaining and jealousy.
