I just think that Carlisle’s decision to reduce KP’s role to “stand in the corner and be ready to catch and shoot” was a big reason it didn’t work out on the Mavs. undoubtedly KP wasn’t as good as a post player as he is now but his role in Dallas was almost insulting to his talent. they could’ve easily gotten him some easy baskets with some pick and pops or rim runs but they almost completely stopped going to that PnR by the end of his tenure in Dallas

at the end of the day though I think KP needed to go to Washington where he’d have a lot more freedom to operate not playing with Luka/Carlisle and more importantly no pressure to win, that situation helped him really hone his game and now the Celtics are getting a much better version of him than Dallas got
