If you're that worried about the catcher, then either the catcher is much worse than Barrett defensively, or you're paranoid. The baserunning argument has some merit. However, with Blanco behind the plate, don't you worry about run support a little more? As long as the guy behind the plate can catch the ball, can manage to get his body in front of balls in the dirt, and can avoid throwing the ball into center field on throws down to second, then a pitcher should be comfortable. You might be assuming that pitchers are robots and don't think about these things. What they should think and what they do think may not happen as we would like them to. Look, I'm not saying it's a all or nothing thing which a lot of people seem to think. I like Barrett but he needs to improve in certain aspects of the game. I don't think he will defensively at this age so IMO it's always a good idea to look and see how the Cubs can improve their team and if Barrett is part of that equation so regarding run support I also have to think about how many runs he gives up. Barrett has problems catching the ball and blocking the balls in the dirt. His slow glove and body bother me as it also may bother the pitchers. I don't know how much it effects the pitchers but I would look into it. Winning may be the effect the pitchers need and then Barretts D could be over looked but if Barrett does have them not thinking about their job then let's find out why and have the staff talk this over and find a solution.
