Maybe there were off ice things that made him reluctant. Everyone has top toed around it but anyone I’ve heard (Rayzor, Petey, Rivet, Gionta) have all intimated that Jack was not a good dude. How he treated team employees, his attitude at the rink, was subpar. Hard to say what anyone is like without knowing them. Sam seems like a good dude but he was also BFFs with Jack so he was at least a party to the questionable behavior.
