Two huge rivalry games on Saturday will play a big role in helping shape this year’s College Football Playoff field. And two home underdogs will try their best to pull off upsets and hurt their opponents’ chances of playing for the national championship.

The Auburn Tigers (9-2) figure to have a better shot against the Alabama Crimson Tide (11-0) as 5-point home dogs after opening at +4.5 for Saturday’s Iron Bowl matchup. The Tigers have already handed one previously unbeaten team their first loss when they routed the Georgia Bulldogs (10-1) two weeks ago 40-17 to put themselves into the mix.

Auburn has won 11 straight home games but has lost seven of the past nine meetings with Alabama. Sportsbooks will likely need the Tigers to cover the spread.
