Mine are:
CJ McCollum - if Portland decides the backcourt is redundant (after a playoff fail?), they could make him available. He'd be 25ppg from day one if given the keys in ORL. Fournier could replace his complimentary scoring to Dame, and a high pick and another piece, Simmons maybe makes Portland a more dangerous team if Dame continues his near-MVP tear. To Orl, he becomes like Harden to HOU.
Kemba Walker-lead guard, fiery, scorer, would be the best guy on the team from day 1. Chip on his shoulder, etc
2nd Tier:
Marcus Smart -NOT the same class as the others, but demanding, fierce competitor and defender, intangible guy. Would be great next to a young facilitator like Doncic or Trae. Could become available as Ainge will have Hayward back and an extra pick-may not want to pay.
Capable of occasional breakout scoring games when needed. No fear, possibly a breakthrough candidate.
Patrick Beverly - BIG chip on his shoulder, like Smart + a 3pt shot. Not sure why he'd be available, but...
Isaiah Thomas -BIGGEST chip on his shoulder in the league, lots of question marks but maybe with a limited contract, etc
Bledsoe - Wanted him when MIL got him, wouldn't be deeply in Giannis' shadow.
Brogdon - not sure of his mentality or availability but interesting, what could he do if given the keys to a young team?
Rozier - maybe Ainge has to make a choice between him and Smart? Is he a hidden gem behind Kyrie?
( now I'm really reaching

Frank Mason - is he hidden behind Fox ready to be the next King escapee? Mature leader, big Chip on his shoulder
Dejounte Murray -is he a singular talent hidden in a system? Could he be what Fultz was supposed to be(or will be)?
Dante Exum-did he lose his spot before he was ever well enough to compete for it?
Any mature leaders with an Alpha sense coming out(maybe 2nd round surprises better suited to NBA?) Brunson, Shae...
