I think that's because if a catcher sucks at hitting, people automatically assume he's good defensively. Jason Kendall is my favorite example. He was always considered a great hitter with an awful glove when he was in Pittsburgh. Now all the talking heads wont shut up about what a great defender he is. To be fair, he was one of the worst at throwing out baserunners before Ned Yost got to him. Jason Kendall's rSB from 2003 through 2010. -4, +2, -4, +4, -8, +8, -2, -1 Yeah, he had one very good year after going to the Brewers... but he's coasting on the reputation of a fluke year.
