This thing came up in a discussion with my friend about Crosby's next contract. His obligation to the NHLPA is definitely a factor in this decision. At the same time, the NHLPA can only benefit from him. I don't see him as the kind of person that just jumps out of the NHLPA, but does one need to be in the PA? I seem to remember Mario and Gretz both not in it at one time or another. Jordan the same in the NBA along with other minor players here and there throughout history. Most recently, I can think of Bonds as one who isn't in the association. Basically, is there any stipulation in the CBA or anywhere else that would say a player must be in the PA to play for an NHL team?
