Davis is good.
Brown, maybe maybe will end up ok.
Rundle is way too slow and unathletic for D2, Moye is terrible, just terrible and Owens is like a second walkon. Parker has a 45 rebounding, not good enough for D2.
Roark is probably ok, but would be better if his block rating wasn't worse than most SG's.
Overall, you need more everything. High potential is good, but a high potential 20 is worse than an average potential 50 in a category.
