I may give James Jones credit for hiring Monty, signing Cam Payne and Jae Crowder, also putting the Finals team together, but not a lot more.
Monty hire, I suppose makes sense. He was a future scapegoat by JJ but a good hire that I'll give JJ credit for.
Monty had a relationship with Cam Payne and suggested him to the team, like he also did with Shamet a little while later. So JJ doesn't deserve credit for that solely.
Crowder is a weird one. The ending here soured me on him and then more came out and I realized he wasnt to blame. He did well here but ultimately was a poor fit next to Ayton at PF. Any credit JJ deserves for bringing in Crowder is cancelled out by how his last year here played out. It's the GM's job to make the coach and player sitA down and solve their issues and we all saw that didn't happen. JJ let Crowder sit for months and his value dissipate also.
