Well, the Silver Slugger is a vote, so personalities of the voters come in to play.

My first guess as to why Buster didn't get it is that he didn't play enough : he had under 300 ABs as a catcher (he had 113 ABs as a 1B, remember). I bet that's the same reason that G Soto of the Cubs got passed over as well (he had an *amazing* year at the plate, better than Buster, but only had about 300 ABs). Both Posey (75) and Soto (97) started under 100 games at catcher, while McCann started almost 130 games. I have no argument with McCann getting it.
