How about Denver? A package based around Jamal Murray, some youth and picks. That is more attractive than Brooklyn. Harden gets to play with the great Jokic.
If I am the Clippers, I'm offering PG13 for Harden. See if I get any takers. Houston might do it to avoid a rebuild. Harden + Kawhi is big time.
If I'm Utah, I try his agent and see if there is any chance Harden would go there to play with Gobert. I'd deal Donovan Mitchell for Harden if Harden would stay. A Harden-Gobert partnership would be dangerous. Bogdanovic, Ingles, Conley, Favors. That team is a title contender. Heck, I might do the trade anyway because I don't see that Jazz group getting to the a title any other way. Take the risk like Toronto did with Kawhi. Be brave.
