Total crap. There have been 18 semifinal games in the CFP era. There have been only 5 games decided by 10 points or less (two last year), 7 by 11 to 21 points, and 6 by >21 points. The Cincinnati game was decided by 21 points which is in the mid range of CFP playoff games.
Do you remember these games?
Oregon 59, FSU 20
Alabama 30, Michigan St. 0
Alabama 24, Washington 7
Clemson 31, Ohio St. 0
Clemson 30, Notre Dame 3
Alabama 24, Clemson 6
LSU 62, Oklahoma 28
Georgia 34, Michigan 11
Only 3 teams that year held Alabama to fewer points than Cincinnati (27):
Auburn 24
LSU 20
Georgia 18 (Championship game)
Alabama scored more points against:
Miami 44
Florida 31
Ole Miss. 42
Texas A&M. 38
Miss. St. 49
Tennessee. 52
Arkansas. 42
Georgia. 41
Cincinnati clearly belonged as they had 9 players drafted in that year's NFL draft, which was 3rd most of any school.
