Honestly an IT/Horford/PG13/Hayward lineup would be unlikely to win a championship, and would be absurdly expensive to keep together next year.
Aside from the 2004 Pistons, what was the last team to win an NBA championship without a top-10 player?
We might have just dodged a major bullet.
I think you could make the case that Paul George is a top 10 player
Maybe.
But since the 1980's every title team was led by someone better than him except for maybe the 2004 Pistons.
If he's our best player it's highly unlikely we win a championship.
This is the cold, hard reality of the NBA.
The vast majority of championship teams are led by all-time great players like LeBron, MJ, Russell, Duncan, Kobe, Bird, Kareem, Shaq, Hakeem etc.
