I was completely with Kimmie until recently. As I said in another thread, I love those "big arms". I like seeing a catcher throw out a base stealer by 10' with a perfect throw and that makes Vaz fun for me to watch. Plus I like the way Vaz frames pitches as opposed to Leon.
However, when I now look at our two current catchers I see them as being about equal. What Vaz lacks in offense he makes up for in defense and vice versa with Leon. Momentum being what it is I see the starting catching position as being what it is until Leon somehow proves he can't do the job. Then Vaz will get a shot.
I'm not qualified to get into the discussion of whether the pitchers like one catcher better than the other or into the aspect of game calling. I'll leave that to the people in the clubhouse. From what I see, looking at the bigger picture, the Sox are fortunate to have two very good catchers who are essentially interchangeable. We can throw either of them out there and not worry about whether they'll cost the team the game. I'll go with that for now.
