Howard - think a more raw version of MCW. I'm not saying he's ever going to be as good as MCW, but that's who his game and body type remind me of. He's still learning to play PG, though, and is - at best - a streaky shooter. He's got a solid handle, he's a good passer but from when I've watched him play, he seems to try to get a little too flashy sometimes and it leads to turnovers.
Richardson - probably the most "ready" to contribute early, though it's going to be tough for him to take minutes from Cooney and Gbinije. Good size and frame, solid but not spectacular athlete, good shooter (he hit 74 threes in 27 games as a senior). He's fundamentally sound, and a scorer, pure and simple. His defense needs work, though.
Lydon - I think in five years we'll look back and realize he was the best player in this class, but from a physical standpoint he needs to hit the weight room hard. 6-8, working on becoming a small forward. He can shoot, he's very athletic. He led the USA U18 team in rebounding last summer, too. I think he's gonna be a Dome favorite sooner than later because he works hard and can throw down some highlight reel dunks as well as knock down threes.
Diagne - a little undersized to play the 5, but we're going to need him to play there at least some. He's more of a 4 but necessity will dictate he rolls over to the 5 depending on 1) Chino's development and 2) Coleman's health. He can be an animal on the glass, and his offensive game is extremely underrated. He's got a smooth looking jumper that he can knock down pretty consistently out to 15 feet. I think he'll surprise people.
