Who needs a #1 center on a team trying to compete anyways? This team just needs more picks and prospects.
But honestly, you don't trade players like Jason Spezza. Spezza is the player that teams dream to take 1st overall in most NHL drafts. We're talking about one of the best players at his position in the NHL, playing at the most sought after position there is. If we had a 30+ year old Spezza in 2008? Maybe. But this team just finished making it to the 2nd round of the playoffs while continuing the re-build plan. It's almost over. Why the hell do we take 5 steps back with a trade like this? Sure, he'll be a bit older than the rest of the time while they hit their prime. Using that same logic, should we have dealt Alfie when he was 30+ before our Finals run because he was older than the core of the team? No.
You don't need to look at the names to tell you this is a bad trade for us due to where this team is right now. #1 center (+) for two valuable prospects. This severely impacts how the team competes for the next few seasons and will then see all of our young stars hitting UFA status at the exact same time, all looking to get paid.
This is the time where we make moves to improve our play now. Give up assets that are potentially valuable in the future for those that can produce now. You know, rather than making us mediocre now and having a chance at being good in 4-5 years (where we still have a huge hole at 1st line center).
Seriously, who would be our (permanent) 1st line center? Turris?
EDIT: Looking at that future line-up, we would need EVERYTHING to pan out just peachy. Stone becomes the 1st line winger. Nich is a sure fire 1st line winger. Turris evolves past his 2nd line duties. I'd say the chances of that 1st line being a Stanley Cup winning 1st line are pretty damn slim unless Stone and Turris step their games up tremendously. Jesus.
