Before playing against the Baylor Bears, Collin Klein was the overwhelming favorite to win the 2012 Heisman Trophy. Now, things are much less certain.

Klein is definitely still the favorite, but his three interceptions on Saturday certainly aren't helping his candidacy. The senior quarterback also watched his team fall out of the national championship race after being No. 1 in the country for only a week.

Of course, Klein has some competition with Johnny Manziel. The freshman quarterback for Texas A&M known as "Johnny Football" has taken the game by storm. Manziel engineered a massive upset over the Alabama Crimson Tide two weeks ago and has to be considered a dark-horse to win the award.

If Manziel could do it, he would become the first freshman ever to hoist the Heisman.

Other worthy candidates include Manti Te'o of the Notre Dame Fighting Irish. Te'o has been sensational for the nation's top team, racking up 96 tackles and six interceptions while representing the heart and soul of his squad.
