There was a lot of dramatic movement in this bracket, which is still possible this early in the season because one game can still have a significant impact on a team's profile. The later we get in the season, the less of an impact one game can have because it's a smaller part of a team's overall schedule.
UConn was the big mover after winning at Memphis, but that wasn't the only thing working for the Huskies. Indiana beat Wisconsin earlier this week, which wasn't quite enough to put the Hoosiers in the bracket, but it did make the Huskies' win over them earlier in the season look a lot better.
Finally, Colorado dropped after losing at home to UCLA in its first game without its best player, Spencer Dinwiddie. Part of that drop is that the loss hurts the Buffaloes' profile, but also because they didn't really look all that competitive with their new roster. The Buffs have to prove themselves all over again to the committee. They won't ignore what CU has done in the past, but if they don't look like a tournament team without Dinwiddie over the next two months, there's a good chance they won't be a tournament team.
