Okay so Shamet:
He's a 6'4 combo-guard with a 6'11 wingspan, subpar strength, a quick but not explosive first step, above average handles, great shooting mechanics.
Defensively he's overrated imo. He's got a high IQ, moves decently well with his feet.
He still has massive issues when he gets overpowered by bigger and stronger players, something that will happen much more in the NBA. He's got a narrow frame that won't pack a lot of muscle so I doubt his build is going to change much (but if it does there could be some unexpected upside).
He has big issues navigating through screens. He can't really absorb the contact and struggles avoiding them. There are going to be many more phyiscal screens in the NBA than in college, so that part is going to be worse. Right now he'll be killed in PnRs which is why I don't see him having imediate impact as a PG.
He also struggles to keep up with players with an explosive first step. He isn't a quick-twitch athelte, but with his build, technique and footwork he should do better and I expect him to do better.
He's best used as a team defender that knows when to help. Has quick hands, but won't get too many steals or deflections. Doesn't really anticipate plays. Fronts bigger players on switches.
Offensively he's got above average handles (but not yet on the level of NBA PGs) that will allow him to bring up the ball versus pressure. He's got a nice burst and combined with his handles can beat a man off the dribble in college. When he reaches the rim, he's using craftieness to finish. Doesn't like contact and isn't all too great vertically. Doesn't get to the line too often either. Wether he will be good enough to pass by and finish versus NBA athletes is yet to be seen. I have my doubts.
I like him much more as a shooter off the dribble. He's got very good mechanics, good footwork on the stepback and a one motion quick release. His release point is a bit low and his arc is slightly flat, but I don't have doubts that he's going to get his shot off.
Off ball he moves well, always ready to catch and shoot. Quick trigger there also. Haven't seen him attack closeouts all that much. He's using jab stepts though to create space to rise and fire.
He's also a very clean passer. Makes easy reads, finds the open man, low TOs. Won't wow you with his passes. Can hit the roll man in PnR's but doesn't use all the angles. Very unselfish but doesn't have elite vision or feel.
Don't think he's a true PG or SG. Could go either way. Solidifying his skillset to serve one of those two roles would be his best bet to be a starter. He also needs to improve his body massively as that is another road to upside. Could do well as a secondary/tertiary ball handler (e.g. on the 76ers next to Simmons).
Imo his game vs. Cincinnati tells you a lot about him:
Edit: I have a hard time rating him above Elie Okobo. Pretty similar in some aspects but Okobo just has less question marks.
