Actually, no. I'm not making that assumption. What I'm assuming is that pitchers are professionals and that if they've made the major leagues they no how to go about their job. If a catcher is so bad that you're worried on every pitch whether he is going to catch it or not, then that person shouldn't ever be catching. Barrett is nowhere near that bad. He's adequate. He has four passed balls this year in just over 930 innings. Blanco has two passed balls in just under 370 innings. Blanco's ratio is actually worse. In fact, Barrett is actually on the low end as far as number of passed balls when you look at catchers who have caught 800 innings this season. I'll admit, his throwing does leave a bit to be desired, but there are a lot of catchers that don't throw well. Kendall, V. Martinez, and Lieberthal have been as bad, if not worse, at throwing out base-runners. Zaun, Lo Duca, Vartiez, and Pierzynski haven't been much better. Sure, a certain level of comfort comes with having a defensively-gifted catcher. A certain level of comfort also comes knowing that you have one less weak spot in the lineup when Barrett is playing. I think his mistakes get magnified on this board, since most of us see him play more than other catchers around the league. However, I'd bet that at worst he's probably middle of the pack or (more likely) just slightly below that when compared to other starting catchers at the major league level. Again, I am not saying I don't want Barrett to be the Cubs catcher. The two points I am making or trying to make are that: A: Does Barrett have an effect on the Cub pitchers mentally when they pitch. It's not that the pitchers may worry about him catching the ball all the time but if it even enters their thoughts. Professional yes but they are not perfect. B: The plus/minus of a catchers offensive/defensive and leadership abilities and how they effect the team. As I've said many times that Barrett hits well enough to keep himself in the lineup and since the Cubs have too many holes in their offense it doesn't make sense to trade him unless it's a deal that can improve the team.
