Stastny is 2 years younger. That's not "much younger".
3 years, actually. Which is quite a bit
We did get production from our centers, too. Koivu scored at .83 PPG, Granlund and Haula both had great seasons.
Haula had a great season for what we expected. However, why not have 4 good centers. Just because we sign Stastny doesn't mean we think either of them is bad, we just value the position and want all that we can get there. Whats wrong with having 4 solid centers? Someone is going to get injured, we're guaranteed a suitable replacement. Is that so bad?
Koivu is not a goal scorer, and Granlund and Haula are still young, so I wouldn't worry too much about that. All of those three players are important for us, all in their own way. Just because a player isn't +20 goal scorer doesn't mean that he's a part of a problem (that I don't even think we have).
Should we continue to make the excuse of 'their young' when they are in the NHL. We should be able to classify as someone as an NHL player or not an NHL player. Since they are both, age shouldn't be held against them, as it works for them in most cases. If a 1st line center with bonafide #1 PP time scores 11 goals. There is a problem. You are right. Just because he doesn't score goals, doesn't mean there is a problem. But since he doesn't get as many assists to make up for his lack of production makes it unpassable. Koivu tied for 88th among all centers in goal scoring playing with great personnel. That, is the problem.
Also, you do realize how good guys like Granlund and Koivu are at setting guys up for goals, right? Koivu and Granlund had the most primary assists per 60 minutes, according to
behindthenet.ca.
Koivu was 33rd among all centers in that statistic and Granlund was 57th. Low for both if we consider them a '1st line' and '2nd line' center.
Koivu had screws in his ankle. That's going to slow him down. Also, on an 82 game pace, Koivu would have had ~14 goals.
Meh.
I'd rather keep Koivu. Even more so when we'd have to most likely give up a lot of money to sign him. There will be many, many other teams pursuing him as well.
But, if you have the opportunity to have all three, why not take it?
