zib has a history of injury. hayes has been pretty much bullet proof.
they are close in age
its a matter of preference and opinion as to who's more talented or has higher upside.
as for whats not opinion lets look at some numbers.
mika 25 yrs old 437 games played. 260 points. .59 PPG 113 goals. .25 GPG
hayes 26 yrs old 338 games played. 191 points .56 PPG 78 goals .23 GPG
very close. mika higher offensive upside with that right shot. KH better 2 way player and better defensively. problem is, the numbers show them to be virtually identical over their careers production wise.
i like both of them.
it comes down to do we keep both or move one of them.
my opinion is there isnt really alot of difference and both are quality 2C's. an argument can be made to move or keep either.
the rest is just preference.
Keeping in mind, that the numbers you're including for Mika covers two years of him playing as an 18-20 year old, which drags his numbers down. That's why I went with the last five years, which paints a different picture, with overlap in the NHL, and a growing separation emerging.
It's kind of like the Andersson vs. the other prospects debate where there is a tendency to take Andersson's floor projections and compare them to other players ceilings.
But when we look at the time when both were in their 20s, and playing in the NHL at the same time, the difference between the two becomes significantly more pronounced.
While there is the argument that Hayes is playing better than his numbers, he's still actually on pace for the second lower goal total of his career and isn't on a 50 point pace.
Zibanejad on the other hand, has essentially picked up where he left off last season and continues to climb.
If anything, I'd argue the gap between the two players is much closer defensively than it is offensively.
Going beyond the numbers for a second, even the internal debate tends to differ. With Zibanejad we debate whether he is a first line center, or an elite second line center. With Hayes, we debate where he falls in the spectrum of second line centers. So I feel like there's at least half a tier of difference, maybe substantially more in those discussions.
