I havent read all of the recent comments about Tek calling a good game or not. But here is my opinion...Whether he does or not, the pitchers believe he does. that extra confidence is likely just as important as whether it is true or not.
I do believe he does call a good game. He knows every hitter they are playing, he knows what they like to swing at and what they dont like to swing it.
His hitting sucks, but in all actuality, to get a catcher who has a 260-270 avg for example, really isnt a lot of extra hits throughout the year. his defense makes up for the hole in the lineup.
