At the PG position, McLaughlin is really nice in class of 2014. For 2015, Dorsey (along with Marcus Lovett and Aaron Holiday) is one of the elite PGs. Barefield, also 2015, is just a small step below Dorsey. I haven't seen Cushan Allen (2015), but his HS stats are not D1 level, 'yet' (3 ppg, 11% from 3 pt range, 6 assists and 15 TOs total). He obviously has next year to improve on those numbers. He doesn't get much burn for a good but not great team.
At the wing (SF or SG), I would take Aaron ('14) over Hamilton ('14). But they are both quite good. Aaron is now at Rainer Beach in Seattle area. Hamilton plays for a stacked St. John Bosco team (with Dorsey). Boatwright ('15), shoots lights out and has improved his ball handling and driving, great size for the wing.
Haven't seen Rabb either, but he is considered the cream of the crop in Cali at the PF for 2015.
Everyone loves KO out here! He is such a great example!
