In the interest of fun and boredom since the season is over:
SportsLine simulations show how the Buckeyes and UCF Knights would fare against Alabama and Georgia, if these four teams were in the Playoff.
After the simulations:
Bama vs OSU: Bama would win 60% of the time, OSU would win 40% of the time.
Bama vs UCF: Bama would win 80% of the time, UCF would win 20% of the time.
OSU vs UGA: Ohio State would win 65% of the time, UGA would win 35% of the time.
UCF vs. UGA: UGA would win 57% of the time, UCF would win 43% of the time.
