Ohio State already was a likely lock to be in Lexington for the first and second rounds while Wisconsin was ticketed to be in Chicago, but now the Buckeyes also have the inside track for the No. 1 seed in the Midwest regional in St. Louis. Still, Wisconsin is hardly dead for a No. 1.

The only team that you can probably say is untouchable as a top seed is UCLA in the West. The rest are still fluid with Florida losing Saturday and a road game at Tennessee looming, North Carolina going down at Maryland on Sunday and with a road game still to go at Georgia Tech this week, and surging Kansas knocking on the doorstep of the top-seed line.

"I told them [in the locker room that] this was step one," said Matta, wanting to make sure that the Buckeyes also were focused on winning at Michigan and then in the Big Ten tournament in Chicago, where a possible rematch with the Badgers is pending.

Matta briefly contemplated whether this was Oden's final home game for the Buckeyes, and noted that when the crowd was serenading Oden with "one more year," he was as well. The reality, though, is that the Buckeyes aren't concerned about next season. They won the Big Ten right on schedule. Now it's on to the conference tourney and the NCAA title -- just like they've planned from the moment Matta got the class to commit.
