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. It's time for round two in Region 2.

This is pretty chalky.

Region 2 is the only group in our College Football Madness tournament that saw the higher seeds all advance in round one. Every other region had at least one upset, even if it was simply a No. 9 over a No. 8 or a No. 10 over a No. 7.

Not here. Will the favorites keep on winning in this region? Voting is open in round two until Noon ET Thursday, March 27. Click here to vote in Region 1. Click here to vote in Region 3. Click here for the full bracket.

No. 1 Auburn vs. No. 8 Washington

This would be another fun real-life matchup. Both offenses play pretty quickly and Bishop Sankey vs. Tre Mason may be the best running back battle we see all tournament.

Round

No. 4 Central Florida vs. No. 5 Wisconsin

Here's Central Florida's first big-conference test. Will Wisconsin be Baylor? Or will Wisconsin be South Carolina?

Round

No. 3 South Carolina vs. No. 6 Northern Illinois

If Jordan Lynch was stifled by Utah State, he's going to be stifled by Jadeveon Clowney, right?

Round

No. 2 Ohio State vs. No. 7 USC

Is this the best chance for an upset in this region? Did Ed Orgeron get the Trojans In-N-Out for winning in round one?
