Kessel didn't really play on a line with Crosby other than the PP. Prior to last year he actually didn't play with Malkin that much on 5v5 either. He is bad defensively in general, not that domi is a shutdown defensive guy but he is miles better than Kessel defensively. Overall kessel is the better player, not by a massive gap, but he is better.

Pens should have fired Sullivan and kept Kessel.

Hahahahahaahahhahahahahahahahahahahahaahahahaa.

the question isn't in 10 years, right now Kessel is obviously the better player. In 5-10 years Domi will obviously better(kessel probably wont be in the league unless he pulls a Jagr)

Kessel 55GP 11G 20A 31P -21
Domi 55GP 13G 23A 36P +4

Kessel isn't even the better player in the first year...

Kessel did go to an anemic offense to be fair, but yes he hasn't been that good for Arizona, now why don't you compare their numbers last year?

If you scroll to the earlier comments, I said Kessel had so many points because he was playing with Malkin and Crosby while Domi was by himself. I was then told that Kessel is still a way better player than Domi without those players.

system matters a lot, even when you aren't actively playing on a line with Malkin and Crosby(which at his most arguably most effective time, Phil was playing with Bonino and Hagelin, not Sid or Geno) that doesn't mean you don't benefit from a style a team as a whole plays.
