Here's an unconventional pick - 2001. Yes, Emeka was about top 100. Ben Gordon was pretty high, and I thought Hazleton was fairly high. No recollection on Chad Wise. But - end of the day, we get draft picks 2 and 3, and two superstars might trump four top 100 players, especially after taking home a title. I know, this is sort of a hybrid between on paper and net results, but I have a hard time leaving out that class, even if only two players ended up being extremely significant contributors.
Hazelton was in the Caron/Taliek/Selvie class, not the Emeka/Ben class. Mike Hayes and Chad Wise came in with Emeka and Ben. While the class obviously turned out to be great because of those two, on paper it initially looked pretty poor for UConn standards.
The original intent of the post was about how the class looked going in, not necessarily how it turned out, which are two completely different discussions. For a 4 man class, the Caron class may have been the best, with 2 McD's AA's (albeit Hazelton should not have been one, but still a top 50 recruit), a top 10 player in Caron who was a post grad and therefore could not be a McD AA, and the JuCo player of the year in Selvie.
If we get Jackson, this one will definitely be up there. If you compare it to other "big" classes (6 plus), this would be ahead of the Shabazz/Roscoe/Lamb class (only one top 50 guy in Roscoe, Shabazz/Lamb both top 100 as would have Giffey been if he was ranked). I think a good comparison is the 2006 class of Stanley/Hasheem/Kelly/Dyson, etc. Stanley was top 25 even though he wasn't a burger boy, and Hasheem I believe ended up in the top 30 (was tough to rank since he hadn't been in the US long). Kelly was top 50, Dyson and Wiggins were both top 70 type guys, and even Mandeldove was a borderline top 100 guy. Eaves and Edwards were lower ranked 3 star types, similar to Diarra and Vital although I think Diarra and Vital are better.
Justin would give us four top 75 type guys and two top 150 guys, compared to five top 75 guys, a top 125ish guy, and two top 250 type guys.
