Vegas odds has the Rangers 7/5 odds of winning it all. Kings are 3/2. Blackhawks are 3/1.
The Rangers have the best odds because their series is 3-1. I bet the odds change dramatically in the favor of the WCF winner no matter who wins the ECF.
True, if you were looking to bet the Rangers there doesn't seem to be any reason not to wait.
I can hear Therrien yelling from Montreal, "Le Goalie.murder! Suspend him!"
