We're moving between different sports a lot at the start of this list, and here's another one. Steve Young is the first former NFL player to make the grade, although looking at his high school figures, he could have chosen to go ahead with just about any sport he wanted to. At one point he was captain of the football, baseball and basketball teams at the same time. There's a certain allure to being an all star quarterback, though, and the chance to be exactly that won out for Young.
Young spent the bulk of his career at the San Francisco 49ers, where after a long wait to really establish himself as a regular first choice pick, he went on to become league MVP twice. Younger readers may not remember his playing career at all, though - he moved into doing commentary and analysis for football games after he retired and has been a regular face with ESPN on Monday Night Football.
