Trevor Lawrence threw for 327 yards and three touchdowns and No. 2 Clemson beat No. 3 Notre Dame 30-3 on Saturday in the Cotton Bowl to reach the College Football Playoff championship game for the third time in four seasons.

The Tigers (14-0) will play either No. 1 Alabama — for a fourth straight season in the playoff — or No. 4 Oklahoma on Jan. 7 in Santa Clara, California.

Clemson’s overpowering and experienced defensive line smothered Ian Book and the Fighting Irish (12-1). On offense, freshmen led the way. Lawrence was 27 for 39 and did not throw an interception against a Notre Dame defense that had been one of the best on the country. Freshman receiver Justyn Ross had six catches for 148 yards and two long touchdowns.
