He's first on the list because he's the one free agent that Boston has the best chance to sign. Free agents rarely move for a lot of reasons, amongst them:Just curious why we're only talking about Hayward, which is pure speculation and he's not even a great roster fit.
- Pure inertia. They've been in one situation for a long time and its familiarity provides a certain comfort factor, Their history with the coaching staff and organization makes it easier to stay.
- Money. The home team can usually offer a lot more than other teams can, and it can be tough to turn down those millions.
- Lifestyle factors. Sometimes the community factors play a real role. For example I can tell you for a fact that one thing NBA players like about LA is that there are so many celebrities that live there their presence isn't a big deal. Sometimes players are young and like the nightlife of places like New York, LA, or Miami. Sometimes the careers of spouses play a role (Carmelo Anthony). Sometimes players like living quiet suburban lives where they're playing (Garnett fit in this category).
#1 doesn't help the Jazz as much given that Hayward is already familiar with Boston's coaching staff, having known Stevens half his life. He also has a somewhat rocky history with the Jazz. Worse still, they look like they've peaked, given how average the rest of their draftees outside Gobert have been.
The Jazz are also about to get a lot more expensive, making it harder to add talent around him. So much like Horford, he may well decide that the time has come to move on if he hopes to compete for a title. Boston already has two star level players, two more high draft picks to add more talent, and the ability to trade for someone like Paul George to add a fourth star. These are things the Jazz can't really match.
#3 is an advantage for the Jazz as Hayward is married with children and unlikely to value nightlife factors, but then again neither Hayward nor his wife have any lasting connection to Salt Lake City and it's just as easy to find quiet suburban homes in eastern Mass as anywhere else. So #3 might not be a big enough advantage for the Jazz to hang on.
It's a lot harder to overcome those factors with the other available free agents, but with Hayward Boston has its optimal chance.
