The idea of any college team beating an NFL team is laughable. Everyone is talking about the big talent disparity, which is true enough, but there's also the issue of experience and practice. The NCAA limits college practice time - and these players with limited practice time are also comparably young and inexperienced. NFL players dedicate their working lives to pushing themselves to their physical and mental limits on a daily basis and many have done so at that level for years. Any matchup would be a massacre.
