#56. Ronnie Bull, 1962, RB. #3 pick (AFL).
He was also drafted by the Bears in the NFL and he went there instead. He actually lasted quite a while in the NFL, 9 seasons with the Bears and 1 with the Eagles. Over 3,200 yards rushing at a 3.7 pace and almost 1,500 yards receiving. Never made the pro bowl, though, and never put on a Chiefs uniform, so he was a total bust. He was replaced as the Bears' halfback by Gale Sayers, and moved to fullback.
Here's a little info about Ronnie Bull if you can briefly tolerate the Chicago Tribune's annoying popups.
