Personally, I believe that Tomas Kopecky is the 'Hawk most primed for a breakout year.
Not only will he start the year on a line with Hossa and Towes, but Q says he'll also see time on the power play.
I know this wasn't asked, but my pick for "Most Disappointing" is Kyle Beach. If there's one thing the pre-season has shown me, it's that the guy has the hockey IQ of a 1st year pee-wee....all psyched that he finally gets to throw his weight around, but not a damn clue as to what the rest of the game's supposed to be about. Plus, he's a terrible skater.
