Here is the list of players who fit into the Juancho TPE but not the Schroder TPE (so they make between about $6-7 million):
Jae'Sean Tate
Isaac Okoro
Kevon Looney
Cody Martin
Jaylen Suggs
Jaxson Hayes
Khem Birch
Bennedict Mathurin
John Wall
Lonnie Walker IV
Patty Mills
Caleb Martin
Joe Ingles
Bruce Brown Jr.
Onyeka Okungwu
Justin Holliday
Josh Giddey
Rui Hachimura
Rudy Gay
Shaedon Sharpe
Cameron Payne
Otto Porter Jr.
Nassir Little (he signed a rookie extension so his trade salary is $6.4 million).
From that list, there are just a few guys that are reasonably likely to be available for trade:
Cody Martin
Jaxson Hayes
Khem Birch
Justin Holiday
Rui Hachimura
Rudy Gay
Martin has missed most of the year with a knee injury, playing in only 7 games so far, so he doesn't make a lot of sense.
Hayes would be a nice get, but he probably would cost more than we'd like, as he seems like the type of player the Pels would move in a package for a rotation player/starter.
Birch is likely available, but he's out of Toronto's rotation, despite their need for help at the 5, and is owed $7 million next year.
Holiday is someone I've liked, but he's been not good this year. He's out of the Hawks rotation, so it's hard to imagine he'd make it into ours.
Hachimura has been discussed already.
Gay has a TS% of .434 this year and is owed another $6 million or so next year. If the Jazz want to send a 2nd to the C's in a trade, as opposed to the other way around, I'd be on board, but otherwise he won't even beat out Hauser for minutes.
It feels like it's pretty much Hachimura or bust. Maybe Cody Martin if the C's were comfortable with his knee, but the pickings are slim. Everyone else we're interested in with the TPEs will still fit into the Schoeder TPE.
