Why is someone who is listed as 6'2" 215 considered too big to catch in pro-ball? My understanding is that the bigger you are, the more difficult it is to get into a crouch 80,000,000 times without it affecting your knees Yeah, but that seems like it's a matter of needing to move off the position when they're older and further into their post prime years. Buster Posey is 6'1" 220. Jose Molina is 6'2' 250. Salvador Perez is 6'3" 245. Pierzinski is 6'3" 235. Wieters is 6'5" 230. Joe Mauer is 6'5" 230. Mauer just recently moved off catcher at the age of 30. To say even if he has the tools, he's too big to stick at the position seems a little presumptuous with someone so young and there being plenty of examples of guys his size (and bigger) being able to catch well into their 20's and even 30's. If he's got decent catching skills and a solid bat, but he might have to move off the position as his prime years come to close, who cares if he sticks at the position or not? He'll likely be traded or entering free agency by then anyways.
