Projected college basketball rankings after Ohio State upsets second-ranked Purdue

The Chris Holtmann era came to an end in Columbus this week, as the Ohio State Buckeyes fired their head basketball coach. While the long-term answer as to the direction of the program is unclear at the moment, the Buckeyes have something major to celebrate thanks to a narrow win over No. 2-ranked Purdue on Sunday afternoon.

With March Madness just around the corner, the Buckeyes chances of making the tournament are slim. A win over the Boilermakers has OSU sitting at 15-11 and 5-10 in the conference. A late-season run isn't impossible, but it's unlikely.

Ohio State is one of the youngest teams in the Big Ten, with over 70 percent of their minutes going to freshmen or sophomores. Two of their veterans came through on Sunday, however, as sophomore Bruce Thorton and senior Jamison Battle combined for 41 of the team's 73 points. Despite 22 points from Canadian Purdue big man Zach Edey -- standing at 7-4 and 300 pounds -- Ohio State was able to hold Purdue's offense in check just enough late to come away with a win.

Here is the AP Top 25 heading into the week.
