I'm not so sure of that.
Personally - and as a Sens fan I might add - I don't think Spezza should make the team. He is incredibly talented, but is still a work in progress and does make some very questionable giveaways each and every game. I love the guy and he is a great player and an integral part of our first line, but I'm not so sure Crosby wouldn't have close to 40 points playing with Alfredsson and Heatley. Staal as well.
If a hole opens on a scoring line and team Canada brass think they need some creativity and playmaking, then Spezza is probably the guy ahead of Staal and Crosby. He will make goal scorers around him better.
But the scoring lines are set for the most part. They are trying to figure out who should play maybe 8-10 minutes a game on the 4th line and provide depth. Spezza is not the guy for that. If I had to bet, he'd try to impress too much when he is on the ice and get a little too fancy. Behind the back passes shouldn't happen on the 4th line and that isn't what Team Canada is looking for.
Staal, and even Crosby, will be better energy players on a 4th line. Either would be a good choice.
