All you people guessing 30 and 15 averages for dwight howard are crazy, unless he's playing in the WAC or something. Look at shaq. He put up 23.4 and 13.8 with 3.5 blocks as a rookie in the NBA; the season before, as a junior in college, he averaged 24, 14, and 5 blocks. as a freshman, he was around 14, 12 and 3.5 or so. Considering Dwight came in as a rookie averaging 12 and 10 with 1.7 blocks, and in his fourth year, at the same age as rookie shaq, has not approached shaq's scoring or block numbers from his rookie year, there is absolutely no way college dwight's numbers would have dwarfed college shaq's numbers.
the answer is Lebron. he stepped in as a prep to pro rookie with 21, 5.5 5.5 averages. that's ridiculous. He would have been a better college freshman than 'melo, beasley, and durant, all of whom had all-time great freshman seasons.
btw, kobe didn't hit lebron's rookie numbers until season 4.
