Even if Cammalleri has a monster year, I doubt he makes the team over a guy like St. Louis who plays the same style and is better offensively than him. I'd say right now, there are about 10 guys (who didnt get an invite to the camp) ahead of Cammalleri who can play themselves on the team (Iginla, Seguin, Benn, Spezza, Jordan Staal, Marleau, Carter, Moulson, Evander Kane, Hartnell).
Pietrangelo will be on the team, barring an injury. He's one of the best young defensemen out there, who can contribute at both ends.
