Bryce Harper entered the professional ranks with more hype than any other prospect (not named Stephen Strasburg) in baseball history.
He also has more pressure than any other prospect.
"Busts" are a part of life in baseball. Players who have fatal flaws or who succumb to career-ending injuries. Some we can see coming (Matt Bush), some we can't (Jeff Allison). Either way, it's always a depressing thing when it happens.
Take as a primary example, the above-mentioned Bush. The prep shortstop was the No. 1 overall pick back in 2004 by the San Diego Padres.
After just 200 games, the Padres gave up on him as a position prospect. It took another 10 for them to cut bat with him as a pitcher. Now he's a reliever in the Rays organization.
Talk about a bust.
This list is comprised of the players I see as the most likely to "bust" as professional players. It might be this year, or it might be a few years from now, but it will happen, and not even the most talented players in the minors are safe.
