2018 CFB National Championship Odds: Alabama, Clemson, Ohio State Favored

Ohio State and Clemson remain among the top contenders for the 2018 college football national championship, but each saw their odds drop after narrow wins in Week 5.

OddsShark provided the latest chances to win the title, led by Alabama as the odds-on favorite:

Clemson finished last week at +400 (bet $100 to win $400) while Ohio State was right behind at +450, per OddsShark. However, they are each now +550.

The Tigers struggled at home against Syracuse but weathered the injury to Trevor Lawrence to escape with a 27-23 victory.

The Buckeyes had a more impressive victory Saturday, coming from behind to knock off Penn State on the road. Ohio State trailed 26-14 in the fourth quarterback but came through with a resume-building 27-26 win.

Still, oddsmakers saw enough to extend the gap between these teams and Alabama, which earned a 56-14 win over Louisiana.

Meanwhile, Notre Dame had one of the biggest jumps in odds, going from 22-1 before last week to 15-1 as of Monday.

The Irish moved to 5-0 with their 38-17 win over previously unbeaten Stanford, and it only gets easier from here. A road game against Virginia Tech looms next Saturday, but no one else on the schedule is currently ranked. If the team can run the table, it will almost certainly earn a spot in the College Football Playoffs.

The Red River Rivalry matchup between Oklahoma and Texas could also lead to a shift in odds after Week 6.
