This is where you start to sound a little crazy.
"Look Buster, you better f***ing hit this year or else..."
"Or else what?"
"We'll make you play ultimate frisbee with SFF, the career killer."
I like it comes down to an NL pitcher who hasn't worked with him saying, "I've heard that he's a bad teammate." I trust that if he has any issues it'll be taken care of by the current team leadership.
