There is a big difference between IW and Delgado. With Whitehead, I don't think many (if any) questioned that the NBA ability was there. Many (including myself) thought with the way he played down the stretch last year (NCAA tourney game aside) that with another year in college he had a chance to play himself into the 1st Round and guaranteed money. Obviously he got a guarantee from the Nets and rolled the dice. It has worked out as they were terrible so he got a lot of time and ability to show his stuff this year. I was also selfishly hoping he would stay so The Hall could have had a "magical" type season/run...This board was 90/10 against iw leaving and thought he was ruining his life. ..
With Delgado, the talent to play at the NBA level is the question. Can he rebound? Yes. Can he do much else at this point, especially versus NBA talent? The jury is more than out. He was horribly exposed as a defensive liability in the NCAA game vs Arkansas. Imagine what an NBA 4-5 would do to him. Nobody is sure the rebounding will translate to the NBA either. The 4-5's are much more athletic and can overcome being out positioned more than college guys can. Maybe it will/would translate - who knows.
Obviously it sounds like he;s going because he has a fallback of $ playing in the DR or overseas. But to the comparison of what folks thought about Whitehead staying in the draft versus Delgado staying in, it's an apples to oranges comparison IMO.
