What a difference a year makes in college football. If it was 2014, the four undefeated schools left would be a lock to be in the four-team playoff—but, as it is 2013, we could see more controversy in the BCS' last year.

I love watching Twitter and other forms of social media during football season. After each win, three of the four fan bases love to try to make their case for their team playing in the national title game. Alabama is in the driver's seat to play for the title, so Crimson Tide fans have little to complain about. But Baylor, Ohio State and Florida State all want to stay unbeaten to lock up the second spot in the title game.

On social media, I see Ohio State fans feeling disrespected over their 22-game winning streak, Baylor fans feeling they get no respect because the school is not a traditional power and Florida State fans saying their previous seasons should not be held against them.

The teams have one thing in common, which is that all three want to face Alabama. If Alabama can stay undefeated, someone is going to get what they wished for, and they might not like the outcome.

If I had a vote for the Heisman, my top three would be Johnny Manziel, Jameis Winston and A.J. McCarron. Without quarterback Manziel, Texas A&M might not have reached bowl eligibility, as bad as the Aggies defense has been.

Winston has FSU on the verge of its second-straight conference championship and first national title since 1999—although the Seminoles' quarterback could lose my vote depending on the outcome of a sexual-assault charge.

McCarron has Alabama in position for a third-straight national championship. The quarterback should be considered for his play as the one constant in the Tide's last three seasons.
