The problem with Kovalchuk was that we paid for the game-breaking guy that probably peaked between 25 and 27 years old. There is no doubt in my mind that Kovalchuk would have been a productive forward for a LONG time in the NHL, but he simply wasn't the singular guy you could rely on to carry a team with two bad goaltenders and a lackluster group of defensemen. Parise and Kovalchuk worked well together because finally neither one of them had to be THE guy.
No doubt in my mind that Parise was missing Kovalchuk more than Kovalchuk was missing Parise. Even with all of Kovalchuk's injuries and lackluster play this season, he still had more points per game than Parise. I'll apologize in advance for using a small sample to prove any point, but the 11-12 playoffs tell me everything I need to know. Kovalchuk and Parise were split up, Parise played with the most effective forward on the team (Elias), and couldn't outscore the slowest Kovalchuk we will ever see, while Kovalchuk drew the top defensive pairs and Parise got nearly a 60% o-zone start rate.
Kovalchuk rules, Parise drools. It just sucks we got Parise's prime years and Kovalchuk's decline, and not the other way around.
