The difference between Savard, Pronger, Horton, Ohlund, Clowe etc...is they actually had career ending injuries. Unless Hossa gets knocked out during the year, you think they are honestly going to allow a team to purposely circumvent the cap? They warned these teams before the contracts were signed there would be penalties. The new CBA is written to intently punish these teams who circumvent it. If a few guys on a hockey fanboard can figure out the best way to circumvent the cap...you don't think they are aware of it? Just wait...it's going to happen. And wait until Weber retires down the road...that will be a crazy penalty. They didn't let Detroit off the hook with Datsyuk and his 7.5m cap hit this year. Doesn't matter who the team is.
Hossa can just say he has vertigo. With the concussions he had, it's plausible and it's not like it's something that would be easy to disprove.
If he does it that way, instead of retiring, he still gets paid the balance of his contract, to boot, so Hossa does have a financial incentive to play an injury game that benefits the hawks as a byproduct.
I'm sure Bettman wouldn't like that, but it's not clear to me he can do anything to stop it.
Hossa: I'm dizzy on the ice
Doctor: He says he's dizzy on the ice
Bettman: That's convenient. I don't believe it.
Doctor: What do you want me to do about it? He says he's dizzy and I can't tell you he's not.
Challenging something like this is a surefire way for the NHL to get a ton of bad press. It's also something that could be used against them in any future class-action concussion lawsuit.
