I don't really think Yzerman has proven himself as a GM. I don't think Shero has done anything all that impressive Chiarelli has turned the Bruins around and made some good deals, but Boston hasn't won any more than Detroit has.
And for the record, Stevo, is the Jackass guy. Yzerman is Steve or Stevie, Stephen to his mommy or just the Captain. Had to get that off my chest.
