This is not an assist friendly offense for a point guard like Harris, who gets most of his assists from pick and roll/screen plays.
The 1st, wnd, 3rd, and 4th options on this team are to dump it into the post and let the bigs play inside out.
It's an assist friendly offense if ur a big man w. a post game, i suppose, but not for the PG who's job it is to basically walk the ball up the court and dump it and watch.
Also, the Suns would have most likely won a title had it not been for ridiculous circumstances like Amar'e being suspended in the playoffs for leaving the bench.
At the very least, he has proven that he CAN win in the playoffs. Plus, players love his style of play and he's got Olympic gold--both of which would help draw free agents, a problem Utah has faced many times before.
Sure he hasn't won a title yet, but it's not like Corbin has been stockpiling championships either, and ur beloved "jazz offense" and overall system has won a grand total of zero championships in history, so perhaps it's time for a change.
