Depends on your definition of stars. Shouldn't matter whether they are an All Star or not, they should fit together. If your players fit together and you win, they become All Stars. The goal should never be to just add a name to Dame. Lakers had LBJ and AD the last two seasons and didn't get out of the first round one season and didn't make the playoffs in the next.
The Heat don't really have 2 stars. Butler is a semi-star and Bam is whatever. The Celtics have one legit star and one pretty good player. Warriors have one star and a bunch of player who are super rich because they play with him. Anyway, Dame needs to be surrounded by excellent defenders. ALL FOUR positions- excellent defenders. Players like Dort, Marcus Smart, Jonathan Isaac, Jrue Holiday, Mikal Bridges, JJJ, GP2, Herb Jones, Draymond etc. ALL FOUR POSITIONS. These guys aren't "stars" but they are the players that would transform us into a winner.
Dirk won in his 13th season surrounded by solid veteran defenders. None of them were All Stars that season but they were the right pieces to put around him. They beat the Defending Champs (Kobe/Pau), the KD/RW/Harden Thunder and the Wade/LeBron/Bosh Heat to get that title. The key to winning a title with Dame is to find players that fully complement him. Yes, it would be nice to get Giannis or Jokic or Embiid, but that's not happening.
So then you need to think about fit. Dort is exactly the kind of player we should be looking for to start with Dame. Josh Hart is a good option to have too. Or Jrue Holiday. Or Marcus Smart. Not Anfernee Simons, who should be the main ball handler on his own team surrounded by excellent defenders. Simons is not a good enough defender to share the backcourt with Dame. This is pretty simple. I can think of better non-stars who would've helped Embiid out of the second round instead of Harden who couldn't.
It's not about names. Morey will never learn that. I mean, you could make deals to bring us Donovan Mitchell and we could say "Yay, we have another star to play with Dame," but that would be so dumb. I'd rather Dort than Mitchell. Seriously.
