I am certainly not an expert or a scout, just giving my opinion on what I got out of the comments. I am basing my opinion on being a former college athlete and knowing the typical frame of mind those guys are in. It seemed a little off putting to me, but I could be wrong.
Now, regarding the idea that it is more noble to stay in school, I must take issue with you on that. Any person who goes back to school risking injury and potentially losing out on upwards of $50 million dollars (If he realisitcally though he would be a top 3 pick) is clearly not emotionally ready to be a professional. Personally, I think he made the right decision last year by going back to school, because I do not believe he would have been a top 3 pick last year, so this is more of a theoretical arguement. Any rational person, including kids in their early 20's, can certainly deduce that if they get hurt or cannot cut it in the pros, that they can take $20 grand of their millions and go back to finish senior year. Or, he could go to school during the off-season while still playing.
The "athlete's have to finish college arguement" is a fallacy for first round picks who are risking a great deal by doing for free what they could be paid millions for - and also risking not being able to cash in on that lottery ticket if they are injured. Those top 30 or so guys will make more on their first contracts than 95% of college grads will make in their lifetimes. You can always go back to school, an athlete's career is finite.
