Hayton has clanged more pipes than most plumbers this year. Extremely snakebit. He's Arizona's Steve Rucchin doing the dirty work, working the boards, screening goalies, and playing well defensively. He has obvious chemistry with Keller and Schmaltz and enough skill and speed to not look out of place. The sum is greater than the parts even if he's "not a real 1C". That line is extremely more effective with him on it, which is why no-one else has grabbed that spot.
I would be shocked if they moved him given how thin they are at center. Having said that, depending on how contract talks go, he wasn't an Armstrong pick, so maybe they are not as attached to him as they would be otherwise. But barring outrageous contract demands, I'd have to think they keep him. Trading him creates another hole on a roster with plenty of holes already. And because of his toolbox, he's the perfect candidate to move up and down the lineup even if they find an upgrade.
ETA: nothing against Krebs still fighting to carve out his niche at this level, and who is a decent prospect/player who will probably improve, but Hayton is a whopping five months older. I don't see why AZ would trade the guy they know works with their best player. It's not like Hayton has more NHL experience to grab his chance, either.

Hayton has shot between 10 and 20% every year until this year where he's shooting 4.5%. Krebs looks snakebit this year at 4 something percent, too.
