Nobody can deny Thomas getting the single point for the Bruins.... Nobody else showed up to win. 
Thomas is not only a shoo-in for Vezina right now; he should be considered for the Hart trophy for his play up to now.
This has nothing to do with who's better or the future as the Bruins goaltending goes. Rask is a great goalie and will be for the Bruins for years to come.
I think Tim Thomas should be in the same category of a Crosby or Stamkos for what he's accomplishing for the Bruins this year.
