No he isn’t. The only reason people are still saying this at all is because he’s 6’4”. That doesn’t matter though because he plays like he’s 5’9”.
And the thing is, even when healthy, he’s just a terrible excuse for a centerman. He doesn’t play in the dirty areas, is poor defensively, not good along the boards or down low, doesn’t play physical, has average IQ at best, and he can’t win faceoffs. This season he was at 40.3% and it was his career high. His analytics are also terrible. And on top of all that, he simply doesn’t produce.
No team is going to win with a 2C like that. There’s no way to justify playing him at C again.
