Players can gain their reputation throughout their career or by having a few good seasons. However, many of these players keep that reputation even when they begin to decline, so MLB has a number of overrated players.
Other times, players garner more attention and praise than they deserve because of the media. The New York City media is certainly guilty of making a number of players seem better than they are. As a result, it should come as no surprise that there are quite a few New York Yankees on this list.
With sabermetrics, it has become easier to point out some overrated players. They might have numbers that look good at first glace, but once you take a deeper look at them, they don't live up to what was expected from the player.
