Don't forget that goalies are voodoo and you never know where the next surprise playoff performance will be comng from. Remember Murray winning cups with Pittsburgh? I'm pretty sure nobody saw that coming. Maybe Samsonov wins the Conn Smythe, stranger things have happened. Well OK maybe not, but maybe you get my point.
I suppose that as they're subjective terms, success/failure is in the eye of the beholder. If for you 10th overall is a success already no matter what happens in the playoffs that's fine, but is sure as hell isn't my POV.
Oops, you meant Boston I guess, my bad, sorry. Or did you? I'm confused, time to go for a walk and get some air. Cheers!
