You guys railing on Bill Self are hilarious. He's got an 82% winning percentage at Kansas. Sure he's had good players, but he's recruiting them, too.
They've won 11 straight conference regular season championships. Even in the Big 12 that's INSANE. Teams he's coached have made 17 straight NCAA tournaments. Pre-season polls take talent into account (that's pretty much all they take into account). His Kansas teams have finished the same spot or better in the final poll 9 times compared to the pre-season (only twice worse). That's led to 12 straight NCAA tournaments, with the lowest seed being a 4-seed. Teams with talent can miss the tournament (Kentucky 2013), you need good coaching to consistently make it, especially at that high a seed.
Sure he "chokes in March", though. At Kansas his teams have lost in Sweet Sixteens 2 teams, Elite 8 3 times, title game, and 1 Chip win. (so 7 Sweet Sixteen + in 12 years). So more than half his seasons at Kansas have been Sweet Sixteen appearances. (UConn has 5 S16's in that time period).
His choke loses- Last year in Round of 32 (Embiid injury). 2010 Round of 32 (by 1 Farokhmanesh'd in a classic). And two bad Round of 64 losses ('05 by 1 to Bucknell and '06 by 4 to Bradley.) The more times you get to the tournament, the more chances you have of getting upset. They never got blown out, they always had a shot. You're going to lose sometimes, sometimes early on.
