First, Pastrnak and Nylander's effective Cap hits are basically the same. Nylander is 8.75 on the $6.9 mil. Pastranak is 8.89%. Cap hit percentage is more important than dollars.
Second, Nylander had a bad year... and bad luck. Had his shooting percentage been career average, he would have actually paced for close to his career average.
Third, Nylander doesn't need to match Pastrnak's performance to justify his contract. Pastrnak has significantly outperformed his contract. You'd want to compare Nylander to all players who have similar cap hit percentages...not just one guy, who is a bit of a statistical outlier. I mean, Gretzky's last contract was an average of $4.3 million, and we just had Kadri, who was paid around the same.... how could you pay Kadri the same as Gretzky?
Matthews is the biggest question mark on this team. His health has affected his performance. When healthy, and early on in the year, he's been a guy who it's hard to argue isn't one of the top players in the league. At game 21, he was 1.57 PPG last year. 128 point "pace". which would have tied him for the league lead. It appeared as though his shoulder issues slowed him down, more and more as the season went, ultimately requiring surgery. It has been surmised, that he grew up playing in a system that didn't have the same level of physicality, and hits that the CHL, or even Europe might have. I don't know if that's true, but he has been hurt in the same way, a couple of times, and that Trouba hit wasn't much. The Matthews story is going to be one of durability. If he can't find a way to be durable, and not slowed down by injury woes, he will be a player who will earn his contract. If the injuries cause more time off, and also mean a reduced production, he'll be an issue. My personal opinion on the contract, was that they gave him 8 year money, on a 5 year deal... not a gross overpayment, but still too much. I know it's blasphemy to suggest such a thing, but if he has another injury riddled season, I might actually consider seeing what he could be traded for.
