Still mind-boggling that college hoop fans always want any player showing a whiff of NBA potential to come out. Why?
If he has flaws in his game that will be exposed in college they will certainly be exposed at workouts and derail his NBA career. Or he can go back to college and get better and ready for the next level. Staying in school has actually worked out plenty of times, people act like its a death sentence.
For guards, particularly PG's, 2yrs+ of college is often necessary and better for success:
Damian Lilliard - ROOKIE OF THE YEAR BITCHES - 4yrs of college
Steve Nash - 4yrs
Andre Miller - 4yrs
Jameer Nelson - 4yrs
Greivis Vasquez - 4yrs (I wouldn't have put him on this list, but he'll finish 2nd in league in assists)
Kemba Walker - 3yrs
Stephen Curry - 3yrs
Deron Williams - 3yrs
Ty Lawson - 3yrs
Chris Paul - 2yrs
Rajon Rondo - 2yrs
Russell Westbrook - 2yrs
Jason Kidd - 2yrs
Jrue Holiday - 1yr, drafted 17th though
Mike Conley - 1yr, drafted 4th but for first 3yrs was below average NBA PG
Derrick Rose, John Wall, Kryrie Irving - 1yr, all #1 overall picks (obviously you come out when you are #1, neither Wall or Irving has won in NBA yet but I think Irving will be a winner and Wall is finally showing signs of helping his team in his 3rd year).
Conclusion: PG's need more seasoning.
