Buck for the peer reason he has a ton of power
dude hit 15Homers in half a season last year.
He isn't capable of hitting for a high average but he has tremendous pop.
Buck could hit
making him a very valuable catcher b/c very few can hit 25HR. He is also very capable of being this years Victor Martinez and busting out with 30homers and a 275 avg.
Closser is a nice hitter, but he has very little pop in his bat and has showed little power in his career thus far.
Don't get inamered with the fact he hits in Coors, in order to hit homers (even in coors) u need power, and Closser has very little, he is more of a hit for avg guy.
