1. Jimmy Butler needs to get to the rim more
The Heat need Butler to get to the rim more, which would lead to more successful finishes and drive and kicks to teammates for open shots. He had his shot rejected quite a bit this past season, but with a little bit more elevation and dedicated finishing, his shooting percentages around the rim should bounce back.
Miami's spacing could be better if Butler just puts his head down and dedicates himself to that side of the ball. Good things happen when Butler is activated and we've seen that this has been the case since he put that jersey on.
Butler's strategy of sitting in the corner and taking three-point shots was interesting but in retrospect, it was more of a way for Butler to take a break, and he only got away with it because the shots were falling. It's important to floor space, but instead of Tyler Herro driving and kicking for a Butler three, it's fair to say a better outcome would involve the two switching roles.
The Heat don't need Butler's usage rate to rival someone like Luka Doncic, but it being at an all-time low when you're still the big guy who is also looking for a new contract... well... you got to play like a max player to make max money.
