He had 4 assists, which is amazing and stupid on a bad day, but it's not like he just had 4 assists.
He had 4 assists while being a massive plus defensively. He contained Hughes, and Hischier attempted like 2 shots all night with Fox on the ice.
That's what people who don't watch the Rangers don't quite grasp about Fox. He's the only player in the world that has the defensive role he does and scores at the level he does at the same time.
I've said it many times before, it's under-the-radar how little most stars actually care about defense, especially in this day and age.
Zibanejad, to his credit, plays a lot of defense. Mika is a massive matchup center. Gallant uses him to do everything hard. But if you look at the defensive metrics, Zibanejad survives his matchups (and there's something to be said for that); Fox dominates his matchups.
I don't know if Fox is the 2nd best player in the league, and frankly, I'm not interested, but I definitely think he's the 2nd most unique player in the league (McDavid on both counts).
