Welcome to Dr. Saturday's College Football Madness. Ever wondered how the 2013 college football season could have turned out with a 68-team playoff? You've come to the right spot. While 68 teams participate in the NCAA tournament, we're running an expanded college football playoff. And you're in charge. Each matchup is open to a vote and the team with the most votes in each game moves on to the next round.

Two non-BCS schools in the Sweet 16? Yep.

Northern Illinois scored an upset win over South Carolina in the second round of Region 2 and Fresno State beat Arizona State in Region 4. Can they continue their runs? It's not like Ohio State and Michigan State are formidable opponents, right?

Voting for the Sweet 16 in Regions 2 and 4 is open until Noon ET Monday, March 31. You want your favorite school in the Elite Eight? Vote! You can check out Regions 1 and 3 here.


No. 1 Auburn vs. No. 5 Wisconsin

No passing allowed in this game please. It'll be entertaining enough with both teams running the football.


No. 2 Ohio State vs. No. 6 Northern Illinois

Jordan Lynch or Braxton Miller? It's an intriguing decision, isn't it?



No. 1 Michigan State vs. No. 5 Fresno State

Fresno has the offense, Michigan State has the defense. Does Michigan State have the offense to overpower the Fresno defense?


No. 2 Stanford vs. No. 3 Oklahoma

There's a lot of red and white involved in this game, and Oklahoma's run defense is going to be put to the test.
