Agree to disagree, does he have a slow shot at times, yes. Can and does he speed it up? yes. Does his efficiency go down when sped up? I don't know, I don't have those statistics, but I would have to assume yes.
I've played with plenty of people in my life who have had funky shots, and "slow" releases. Who have been able to make a good living for themsleves playing basketball, and didn't have nearly the hype TH has currently (or the intangibles). But, looking at his shot now and saying he won't be able to get it off in the league is not fair in my opinion.
I agree. The biggest thing that matters in the NBA is %. TH is a very accurate shooter and has good range. Sure, he's not going to be running off screens for a catch and shoot, but not many NBA players do that anyway. Guys like Klay and Reddick are "specialists" in that regard. If he can spot up and hit threes at 40% he will have a long NBA career.
