A better player how? Aesthetically... sure, if you think being a better player means upholding basketball praxis of how you think the game should be played. He wouldn't be a better scorer if he played in the paint i) because he doesn't have much of a post game ii) it would take away from his ability to orchestrate the offense from the perimeter iii) it would clog the lane up, when the Warriors offense functions through ball and player movement
Besides it's not like he doesn't score in the paint at all, you often see him taking advantage by posting up a smaller wing/guard when he has the mismatch or taking a big off the dribble and finishing at the rim.
The whole point to him shooting 3s is that it drags defenders out deeper and further away from Curry and Klay, when they want to position themselves behind the arc or get an uncontested layup because Draymon'd man is guarding him out on the perimeter. And the fact that 3s are worth more than 2s - which is really becoming an adage at this point. I don't see how he'd be a better scorer if he replaced his 3-pt attempts with midrange attempts given the fact he'd need to shoot well over 50% on them (which he isn't capable of) to match his 3-pt shooting production, and he would need more shot attempts to equal the production he gets from behind the arc - which would take away shots from better scorers on the team.
but that makes craw 5th
