That said, Harden did show a bunch of really impressive skills at the college level that you could kinda project into the NBA.
College Harden had a 29%AST rate to a 16%TOV rate, a .600 FTr, shot over 60%TS both seasons, these kinds of things. These tend to track well into the NBA, and obviously for Harden they did - particularly the FTr, until they changed how they called stuff recently.
Hardy, so far in the G League, has a 12%AST to a 14%TOV rate, a .149 FTr, and is shooting 44%TS.
It's absolutely unfair to compare Hardy to Harden in his prime, but I think it's a slightly more reasonable thing to compare them both as prospects. It's clear that, at least through 4 games, Hardy is not the prospect Harden was. Which is fine, you don't have to be that good a prospect to be good, but it's worth considering when you're talking about a top 5 pick.
