People keep saying Zibanejad won't age gracefully, but I see no reason to think he will not be productive throughout the deal.
He has a fantastic shot, top tier in the league. That shot doesn't dissappear. So it'll be a weapon through the deal.
He also currently plays pretty heavy. If he is losing a step, cut some weight. He takes very good care of himself.
Concussion issues are overblown. When was his last one? Remember when some guy wearing 87 had those? Can't remember when he got one last.
We're talking about one of the top centers in the game. This isn't when they signed Stepan or when they were looking at Hayes signing. This is a different level of player.
