Curry took 120 less attempts to get to where Mitchell currently is on makes. That’s not necessarily a knock on Mitchell. He’s not a terrible 3 point shooter, but I wouldn’t call him good at it either. He’s pretty average from deep. Curry shot 10% better than Mitchell from 3 his rookie year, but Curry is an all time great shooter so whatever I guess.
My point is, that stat really doesn’t mean anything other than Mitchell is a more integral piece of his team than Curry was his rookie year. That, and Mitchell shoots a whole lot more than Curry did. Mitchell is far less efficient than Curry, in a time when it’s easier to score than ever before.
That being said, there is something to be said about the fact that Mitchell is the only shot creator on his team, and Curry was somewhat of an afterthought for most defenses as a rookie.
