Because no Canucks have gone overseas yet. They're all still here, waiting for an NHL season to get underway. Either they're the most optimistic players in the NHL or the least realistic. Guess we'll see soon enough.
Burrows' agent said he had a lot of offers, but I think many of the players are holding off. Guys like the Twins, Burrows, Bieksa, etc. have kids that they probably don't want to go away from to go overseas.
I respect the players' decisions either way. They've got to do what's best for their families, just as I would in their position, whether that means staying here and focusing on practices or going overseas to supplement themselves financially.
