The patriots often do this and you gotta give em props for that. One of their guards, stephen neal, won the Hodge trophy (wrestling's Heisman) in 1999 but didnt play football.
Also a guy I met at Midwest Lineman Camp in 2004 was Stacy Andrews. He got drafted in the 4th round of the 2004 draft and had only played 50 snaps of football in his whole life, as a senior at Ole Miss. Great story, great guy. He never played ball in HS but he went to Ole Miss on a track scholarship (hammer throw and javelin I think). His senior year he played football too, because he was told he could be drafted. He did get drafted by the Bengals in the 4th round. It was crazy, because the lineman coaches at the camp were mostly linemen from the Bengals and their O-Line coach plus some small school line coaches. So here I am (a high school sophomore), doing drills next to this professional football player who is 6-7, 342 and learning all of the same stuff, even coaching him up a bit and riding around in his brand new Navigator with dub deuces and a ridiculous system. It was pretty cool.
