Would they sell for a premium because of the story?
Yes, I believe they will sell for top dollar. But if I was the owner, they would go with a mug shot of him for destroying private property. There is no way to defend Sale for this act of childish behavior. A grown man walks to the coaches office and says " Coach you mind skipping me today. I don't think I can perform in this jersey. " And if he says no. You just say. " Well I'm not playing today." But no, this guy grabs a pair of shears and goes to town on everyone's jerseys? What's he going to cut up next? Hide the scissors! Here comes Sale!
This guy is a great pitcher. But he'll probably be remembered for cutting up everyone's jerseys, because he didn't want to play baseball.
