Asking people here is kind of irrelevant frankly. Nobody here plays professional hockey, nobody here knows the grind or suffers from the injuries or does the training or travelling.
I'd like to think I'd go. That being said, I also have a girlfriend who misses me, I can't imagine having one and travelling a lot for 8 months of the year. A lot of these guys have young children, it would be hard to me to justify missing my children's youth for a hockey tournament when I play hockey 9 months of the year. It would also be hard for me to justify risking injury and losing out on millions of dollars in the future.
When you're young and healthy it makes sense to go, but as you get older there are a lot more responsibilities to consider.
