Payton Pritchard...might be the next Steph Curry 
I’d settle for Seth Curry.
Seth Curry wasn't as good as rookie PP until he was 25. Think he's got that level covered
but 25 was basically Seth's rookie year as he only played 2 games when he was 23 and 2 games when he was 24 (he had 21 total minutes before landing in Sacramento in his age 25 season). And Pritchard will be 24 during the season, he is old as 2nd year players go.
Older players often (not always obviously i.e. Seth Curry) come in more prepared and perform well, but they also often don't grow like normal rookies do and usually end up with a pretty low ceiling. That is why I don't expect Pritchard to be much more than a backup level player because he would have to go against historical trends to do that. Seth Curry is probably a pretty good comparison of where Pritchard will end up. A guy that could start in the right situation, but is probably best suited as an instant offense type player off the bench.
It's like you're intentionally missing the point. Seth Curry only played that few games because he was simply not good enough. That's the difference. Having totally different starting levels of skill has an impact upon progression.
Sure, but he didn't say Seth Curry the rookie, he said Seth Curry. You know the guy that has never shot below 42.5% from 3 (and has been 45% or better the last 3 seasons) and started for a team that won a playoff series last year.
And Seth Curry is the pretty rare player that enters the league after 4 years of college and actually got significantly better. That isn't typical. Most older rookies enter the league much closer to their peak. That obviously makes sense, but is also borne out time and time and again. There are exceptions (like Seth Curry) so maybe Pritchard is an exception, or maybe he is like most 22 year old rookies that is fairly close to a finished product, in which case Seth Curry would be a pretty good comparison (i.e. a SG in a PG's body that hits 3's at an incredibly high level).
