Cohen may want to include Polk, but he is smart enough to know that it may not work. What's Cohen going to do when Polk pulls him to the side at practice and says, "John, you shouldnt use profanity in front of the players...it's offensive and crude" or "John, I really dont like the way you are handling the SS situation....and while we're talking, I think you change pitchers too often"....
Or even worse, he doesnt pull him off to the side, and says it in front of everybody because his name is on the stadium?
