So the bottom line is that you think the Yankees have a better chance to win games when Chris Stewart catches, and I say that he is irrelevant,and is not a factor in whether this team wins or not. He is not a difference-maker in the slightest IMO over Romine. If you really think that Chris Stewart is some sort of X-Factor - then you are the one who needs to prove that - not me. You (and you alone) are the one singling him out for some strange reason. Lately, you've been on this "he makes them better incremently" kick, as if the 0.02% contribution the guy makes a difference.
Making an argument that Chris Stewart gives the Yankees a better chance to win when this team has so many other factors going on is just you reaching aimlessly to make some sort of point that only you can understand. But I'm sure he, his mother, and his wife appreciate you going there for him.
