If you want to go on about Vegas, there never should have been a game 7. The fact is there was, and that prior to that incorrect call, SJ had done nothing in 4 power plays. I believe SJ was hyper motivated by the sight of Pavs bleeding on the ice, and likely would have scored those goals with or without a 5 min PP. You might disagree, whatever.
Lots of bad calls throughout the playoffs, some went our way, some didn't. It's over, get over it.
Yes, there will be some signing issues, and I believe that EK65 might go elsewhere if the money is right. I think a lot of that will hinge on whether he is healed from the groin issue or if that will linger into next season. Pavs isn't going anywhere IMHO, and neither is Thornton. I believe he would have retired if SJ won the cup, but otherwise he will be back. It will be interesting, but I don't foresee many changes to the roster unless some FA's decide to leave.
