I regularly check the rankings at the end of the weekend to see how teams did during the week.  On ESPN ranking details, they provide the current and past week's results.

This week, I have seen the most losses I have ever seen by the Top 25.  Of the Top 25, only six teams so far won both their games, and 18 teams so far lost at least one game in the past week.  And it wasn't a matter of lots of ranked teams playing each other where one had to lose.

Teams with two wins are:

#1 Villanova

#6 Kansas

#9 North Carolina

#12 Miami

#19 Dayton

#22 Kentucky

#17 Arizona still has a chance as they are playing #23 USC as I am typing this.

Several teams have two losses:

#11 Oregon who some recently had been promoting as a #1 seed

#13 Louisville

#15 Texas A&M

#24 Texas

and potentially USC if they lose to Arizona

This means that next week's rankings will have lots of movement.  It will be a tough year for filling our brackets as there don't seem to be any dominant teams.

If this continues for another couple of weeks, and if the Buckeyes win some of the upcoming games against B1G bubble teams, maybe the Buckeyes can get into the bubble discussion.  Of course, that would require consistently good play which seems to only come in spurts this season.
