Fultz - Brown - Hayward - Porter Jr. - Zizic.
Celtics roster of the future.
I don't know how excited Hayward would be about that. He wants to win now, as does Horford. Kids take awhile to develop.
Age of player when winning first championship:
Stephen Curry: 27
Draymond Green: 25
LeBron James: 28
Dwayne Wade: 24 (2nd title without Shaq: 30)
Paul Pierce: 30
Kobe Bryant: 22 (4th title without Shaq: 30)
Shaquille O'Neal: 28
Tim Duncan: 23 (2nd title with barely alive Robinson: 27)
Michael Jordan: 28
Scottie Pippen: 25
As you can see, two of the younger ones (Wade and Bryant) were helped a lot by peak Shaq. Duncan joined a veteran team that already had David Robinson. Other than that, it's very difficult for a star to win a title before he has 4-6 years experience (as the best or tied for best player on the team).
Anyway, I just mean that Hayward's peak will be ending when Fultz and Brown's are beginning. If Ainge tells him he plans to build for Fultz and Brown's peak, Hayward will walk out of the room.
