They were undefeated out of conference, not just in post-season.
How good was that team? Probably the weakest of UConn's 4 final four teams. I'm not sure they beat any of the other three even with Kemba playing his best.
The 2011 team was one of the better teams that year in the country. Top 16 team easily, very capable of winning against any other top team.
The 1999 team, when healthy was almost unbeatable. They really could have gone undefeated, or been a one loss team if they had stayed healthy and/or gotten a bit lucky against Miami. I would take Rip/KFree/Jake over the 2011 frontcourt all day. I think Ricky would do well enough against Kemba to really slow the 2011 team down. 1999 was also really deep with Jones/Saunders/Wane/Mouring all capable of giving solid minutes.
The 2004 team, when healthy, was probably the best team in the country or at least the most talented. 2011 has no answer for Okafor/Charlie/Boone/Hilton down low, I'm not sure I wouldn't put all four of those ahead of Oriakhi/Smith. They also have no answer for Anderson/Brown at the three spot. The backcourts are a tie at worse if not in favor of 2004.
The 2009 team was probably second best all year, when healthy, at worst top 4. Thabeet would abuse Oriakhi. Adrien would abuse everyone. Stanley would dunk all over Roscoe. AJ and Kemba would be entertaining but fairly even or maybe a slight advantage for Kemba. Dyson, if allowed, would be able to physically disrupt Lamb enough. Freshman Napier versus freshman Kemba off the bench probably favors Kemba. Gavin versus Olander/Okuandu has to go to Gavin. Austrie versus Beverly again goes to Austrie.
Take all of those teams healthy all year and 2011 ends up on the bottom and I love Kemba
