Notes:

• I once again revised my ranking system, hopefully improving it.  I think a few more tweaks may  be needed, though.
• Purdue really should have been in last week.
• Louisville is on the verge of going out of the poll.  Another loss in the near term, and they will.
• In my rankings, Kentucky currently stands at #39.  The 'Cats just need to take care of business to move up, but it will take a win against Louisville to get them into the ballot.
• Pittsburgh moves up on the strength of a road win vs. Florida State.
• Wake Forest was very impressive in two road wins.

Here are the overall Blogpoll rankings:

Notes:

• UNC still unanimous #1.
• Clemson is rapidly improving.  They have beaten a good Miami team and a good Illinois team.  We'll find out more when they battle the Gamecocks on Tuesday, who are playing better than expected under Darren Horn.
  
• Duke beat Xavier twice by crushing them at a neutral site.
• Michigan State's win over Texas reversed their momentum.
• Texas maybe got hit harder than they deserved.  Big win over a good Wisconsin team on the road after the Blogpoll ballots were submitted.
• Purdue easily handling media darling Davidson gave them some upward momentum after dropping two games in a row in late November and early December.
• Duke has beaten 3 of 4 teams in today's poll, including a drubbing of Purdue at Purdue.
• Notre Dame still ranks high despite a questionable schedule.  I may need to revise my calculations to take more SOS into account.  I think UCLA should be lower, also.  They have beaten nobody and lost to both quality teams they have played.
  
• Connecticut beating Gonzaga semi-away is surely validation of them.  I had doubts about them after their close victory over Buffalo, even though it was away.
