Clemson fell to No. 4 in the third College Football Playoff rankings. Louisville moved up yet another spot, this time to No. 5. Here's a look at each team's shot at cracking the final field.
CLEMSON TIGERS
Record: 9-1 (6-1 ACC)
Rank: No. 4
Biggest obstacle: Is there really any at this point? The Tigers lost at home to an unranked team and still remained in the top four. Their final two games are against teams with .500-or-better records, but the biggest remaining hurdle figures to come in the ACC title game, probably against Virginia Tech.
