In a positive sense, definitely Justice Winslow by a large margin. While I thought his mix-tapes were pretty spectacular, he's probably the only Duke freshman in the last 20 years at least who clearly come into college underranked. Justise's composite 247 ranking across all services was 13, which put him in a tier with guys like Ryan Kelly (15), Sulaimon (13), Elliot Williams (16), Gerald Henderson (13) of the past decade. In view of that, it was really stunning to me to see how effective he was on day 1 as shotmaker, playmaker, defender, and rebounder. I thought he'd contribute, but I never thought he would be a legitimate star player as a freshman who really carried us for stretches of the NCAA tournament.
On the letdown, Paulus is definitely the largest letdown -- b/c he really never became anywhere even remotely close to the player I thought he would be even later in his career. Unfortunately, I think that really set the program back, as we recruited with the expectation that he would be the star floor general of our offense for multiple years. As DJ said -- while everyone knew he wasn't the most athletic -- it surprised me how limited he was as a playmaker, and how he never really figured out how to defend the PG position. Even guys like Redick or Scheyer (who did not show up as overwhelming athletes) eventually figured it out by year 3 or 4. With Paulus, it wasn't that he just didn't become Hurley (which is how he was ranked), but that he didn't really even become Aaron Craft. Which is a little sad, b/c you could tell he wanted to be good and seemed like a great guy off the court.
Shav was also a disappointment.
As for Scheyer, I would say that Rivals ranking was just a bit weird. Scheyer was ranked by Scout as a 5* recruit (#20 overall) and came out of Chicago as a legitimate high-school legend (e.g., ESPN Chicago's once ranked him as one of the top 5 best high-school players in the city between 2000-09, ahead of a slew of NBA guys like Dwayne Wade, Andre Iguodola, Shannon Brown, Will Bynum ). It really wasn't a surprise to me at all that he was good.
