I can't think of another player who had a career quite like John Smoltz had. He was a 22nd round draft pick, not the sort of player who seems destined to even make the Major Leagues, much less star there. In his first full season he was an All-Star, and he eventually won a Cy Young. A serious injury sidelined him for a full season though, and then not long after his return, he was moved to the bullpen. Almost immediately he became one of the best closers in the game. Then, after a few years in that role, he shifted back to the starting rotation, and was almost every bit as good as he had been a decade earlier. That's not taking the road less traveled, it's using a machete to carve out a new path entirely.
