If you buy into Hollinger (I generally don't) he has Waiters as the 4th best prospect. I'll be honest, I don't understand how a guard that averaged 12 points, scored better than 20 only twice, and played the 6th man role is so high on everyone's draft board. Russel Westbrook is the exception, not the rule.
Here's Hollinger's top 15:
1. Anthony Davis
2. Thomas Robinson
3. Michael Kidd-Gilchrist
4. Dion Waiters
5. Andre Drummond
6. Quincy Miller
7. Jared Sullinger
8. Terrence Jones
9. John Henson
10. Royce White
11. Bradley Beal
12. Harrison Barnes
13. Tony Wroten
14. Kendall Marshall
15. Marquis Teague
Waiters was without a doubt Syracuse's best player. The issue was that he was a Sophomore who almost transferred after his freshman year because he and Boeheim were not getting along, because other than McNamara and Melo, Boeheim whips freshman around.
Combo that with senior Kris Joseph at the 3, 5th year Senior Scoop Jardine at PG, and Triche who had started for 3 seasons ahead of him.
So he had to come off the bench, but if you watched the team all season, you would know that Waiters was the closer over Jardine and Triche every time. Also he didnt average more than 12 pts, because that team had an NBA center, NBA sf, NBA sg, and really good college players 1-10. So much so that 2 McDonald;s All americans in Christmas and Carter-Williams barely played.
It was speculated that Syracuse had 2 top 25 teams in the country on their team between their bench and their starters.
