Even healthy, Stone has been less reliable in recent years as a point producer than a lot of people seem to think. And while he still might be the best defensive forward of his generation not named Barkov or Bergeron, that's not going to last as he keeps getting less mobile. He had a bounce-back season in 25-26 offensively, but c'mon ... the guy is the oldest 34 year old in league history. The chances of him turning back the clock two seasons in a row are minimal and the chances of him still being that guy 3 seasons from now when that extension ends are real, real slim. I get that Stone is a foundational player for them, but there was no rush to extend him. Why not see how his health holds up this season and then set a value? Chances are pretty good that he'll have other miss significant time (again), and that absolutely would impact the cost of that deal.
