You can say that ("his career would have fallen apart) about most pitchers in the game. Very few pitchers maintain their level of excellence. In 2009-2011 he was very very dominant, especially in 2010. I remember watching his 95+ fastball combined with a 90 mph slider, both with very good location when he was on. All you really n need is two pitches as a RP; as a starter you need at least 3 most of the time. Bard never developed that third reliable pitch-AND he lost the ability to locate. I think his lack of success as a SP played with his head and permanently screwed him up: he lost confidence. Had he stayed in the pen, where he belonged until he had that third pitch, I think he would have had a very good career as a RP.
