There have been a few guys that were pro baseball players concurrent with, or prior to, playing a different sport in college.
Ricky Williams was a Phillies minor leaguer while playing football for Texas. Danny Ainge was a Blue Jays minor/major leaguer while paying basketball at BYU. Chris Weinke was a Blue Jays minor leaguer prior to playing football for Florida State.
Is there an NCAA rule prohibiting Hobbs Kessler from running cross country for NAU while being a pro in track only? Or are cross country and track considered the same sport or does the nature of being a pro "runner" recieving payments from a shoe sponsor change things?
