There's no doubt in my mind Utah will offer him 5 year max. So Celts will have to somehow compete with that. That fifth year will probably be a significant issue, because I doubt Hayward will be worth max money in five years.
I doubt it will be. I mean, Utah needs to offer it because to not do so would be a turn off. But Hayward will not be concerned about not being worth a ton of money in five years, because star players just aren't wired that way. He'll have just turned 27, and expect he'll be at the height of his game until he's 37. Any player of his ability would be.
It won't come down to money. It will come down to on-court success and off-court comfort. He'll be getting a 9-figure deal from someone. At a certain point you can't comprehend the difference. Has he developed the relationships and confidence in Utah enough to stay there for his entire career? Or does the fact that he hasn't played for Stevens in seven years, and yet still is very close with him win out. My guess is the latter.
Also, I'm sorry you can't see how good of a player Hayward is. He's absolutely legit. Imagine that Evan Turner had 25% fewer turnovers, could hit the 3, and was an inch or so taller, and you start to get a picture of Hayward. His game is obviously tailor-made for Stevens offense. He's still below Durant and Cousins on my wish list, but he'd be far from a consolation prize.
