I'd go even cheaper and a bigger gamble/payoff with the prospects as the backup: Yakupov. Probably only one year deal, a third of the money and has proven he can score in the NHL. If he doesn't, another ELC rookie gets a shot with Krejci.
Bruins fans would love/hate Vrbata's streaks and 'casual' attitude and perceived indifference to the game and team.
Just to add Vrbata has been pretty rotten any time he has played outside of Arizona except for the one year on Vancouver.
I get the feeling he doesn't like pressure situations.
He also doesn't play LW...I would like that versatility from a vet UFA just so we can slot the rookies in wherever they're comfortable.
