All I've seen from Baldwin are YouTube clips. Based off of that I basically see a poor man's Kris Dunn besides shooting ability. He's got smoother mechanics than Dunn imo.
One thing I do really like about him is his length. The dudes got crazy length and we need backcourt defenders. I think he could easily step in and help there.
It also seems he's got good vision and at least an average bball iq. His passing impressed me.
On the negative side, he does not move very fluid with the ball. He looks kind of slow and will need to work on driving and finishing.
Dunn and Baldwin are not alike at all:
Dunn is natural PG, who played that position his whole life, has a tight handle and a lot of shiftiness, so he operates by probing due to ability to change direction and gears rapidly. He's not particularly effective at P&R due to inability to pull-up coming off a screen, so everyone just goes under, as he really struggles to shoot on balance in those situations. Dunn has no problem pulling up, when he's already facing the basket, makes a move towards the rim and, if, anticipating, defender tries to shut the lane and give up a bit of space, Dunn can rise and shoot. He likes to create for others, not particularly adept at moving off the ball, though he sometimes use cuts well, so you're drafting Dunn to be your #1-2 offensive option (in terms of touches, not necessarily amount of shots) as you really need him on the ball, so a team will have to at least give him keys to the second unit right from the start.
Baldwin played SG in HS and was recruited as such. But midway through his freshman year coaching stuff noticed, that their new SG is a better playmaker than the nominal PG. Baldwin got control of the team for less than half of his sophomore season, so he's still combo-guard-ish, doesn't have enough experience, instincts, though the fact, that he caught up with Dunn's assist rate after given more control by Conference play this year, is pretty telling. Baldwin seems to be almost always on balance and too upright. It's the second reason after lacking handles, why he seems to lack burst and shiftiness, as you can't change direction quickly in that stance. But it also allows Baldwin to make big steps: if you watch Baldwin's workout video, he makes from corner 3pt line to the basket in 2 steps. That would be his weapon: seeing an opening and covering 15-18 feet, before anyone can react. That actually is Westbrook-like, though at slower speed, of course, so it's not just Baldwin's "full head of speed one man" fastbreaks, that make him look like Russ. Maintaining balance during movement also makes Baldwin a big threat coming off a screen as he can instantly pull up. When Baldwin has to navigate the paint and move side-to-side, situation rapidly deteriorates as he struggles to keep the balance on his shot and doesn't have floater game, which would be a natural answer for him, but here we come back to the fact, that he just didn't have this problem before due to not playing PG, so Baldwin just didn't have the need to develop floater earlier, and there's no time to practice skills during a season. Baldwin is better suited starting his career as next to another playmaking guard and move closer to full-time PG as he masters different parts of PG play.
