Assuming question means exactly 3 years, then leave...
No. Championship seems unlikely in the next 3 years. Not enough to give up all their best assets
I do not believe a championship would be deemed “unlikely” over the next three seasons if they added Davis.
Irving/Hayward/Horford/Davis would be as fearsome a foursome as there is, and that would include if GSW stayed together.
It wouldn’t be guaranteed, but I’d say they would be heavy favorites in the East and most likely the favorite to win the title.
I’d pick current GSW for sure over them. Also Hayward’s a major question mark for the future, and Horford will be 33 in June
1. There is an extremely good chance that Golden State's core is broken up either this season or next. If all four of Curry, Green, Durant and Thompson are still together to start the 2020-21 season, I would be shocked.
2. Horford's age is irrelevant. He won't be asked to be anything more than a glue guy/role player, which, given the nature of his game, he should be able to do until he is 37 or longer. He will no longer be asked to play the best big man on the other team, be the team's best rebounder or even score that much.
3. Yes, Hayward may never be what he was in Utah 2 years ago, but as a #3 option, he wouldn't need to be that good for this team to be a contender. But if he comes back at close to that good, it easily cements this team as a favorite to win it all.
4. The team will still have Smart or Brown or both, plus Baynes and Semi. Morris could also easily be brought back and the team would have their taxpayer MLE to sign a bench rotation player. So the team could be
Irving/Brown/Hayward/Davis/Horford starting with
Smart/Semi/Morris/Baynes/MLE player off the bench.
To me, that smells like a title contending team...easily.
