Ravens-Steelers draws over 15 million viewers as NFL gains bigger audience over CFP games

SMU and Penn State aired at 12 p.m. ET and averaged 6.4 million viewers on the TNT networks.

The Steelers-Ravens matchup averaged 15.4 million viewers on FOX, while Clemson-Texas drew 8.6 million viewers on TNT. 

When the NFL wasn't competing with the College Football Playoffs, the ratings were way up for the other two games. 

The overall average of 10.6 million viewers for the first round of the College Football Playoffs was higher than all but four college games this season.

College football and the NFL will clash again on Saturday, as the NFL has three games throughout the day against a slate of bowl games.
