Just my opinion, but I believe that if Sanders entered the draft this year, he'd go ahead of Mr. amErica - and he deserves to know that.
The NBA cares about 0.5 percent what you've already done, and 99.5 percent what you may be able to do, in the future. Don't forget that; if the NBA drafts you, "you're ready enough," and that's all there is to it. NBA teams are willing to wait for talent to bloom late, just as colleges are.
College fans unanimously feel that under-class prospects "aren't ready," and should stay in school (for the fans' own personal greed) ... NBA fans feel unainmously that "bring him up" and let's see what he can do (also for their own personal gratification).
The difference is that if you stay in school, you get room and board and books (that you'll likely never look at); if you go to the NBA, your'e rich for the rest of your life with any kind of sound financial advise.
If Sanders stays at VCU another year - and it appears he will - he's got more to lose than gain, in terms of his eventual professional riches. Only he and his family are qualified to influence that decision. Everyone else is self-absorbed, and shamefully biased in their analysis.
