A lot of these teams were cut short due to their star player(s) leaving.
The Spurs would have never thought they had a 15-year window, but Duncan was an amazing player and they are a finely ran team.
The Heat had LeBron leave and Bosh become medically inactive. Had that team stayed intact I’m sure they would have made a few more Finals. Thunder got beat by letting Harden go, then seeing Durant walk.
Celtics in 2007 were considered to have a three year window. They came so close 5 seasons later, and if not for injuries would have surely made/won more than they did.
The difference is a GM who understands the cap and continually draft well. Very, very rarely do you see a quality team draft as high as we did the last few years. That can set us up for a sustained run. As the young guys need to get paid, the vets can take less on new contracts.
I think Rozier will be an issue next season and I can see him being delt. I trust Ainge will do the right thing. Smart I feel will be ravines to a modest contract and Baynes should be retained as he’s been very good on Embiid and anchors our defense overall. Rozier is obviously a big piece to our puzzle now but he’s the guy that could possibly get a contract starting 6-7x what he’s going to make next season.
But the rest of the team I believe can be kept together for many years. Hopefully we get good value for Rozier if Ainge HAS to trade him.
