Alabama, Clemson, Notre Dame, and Oklahoma.
Did the committee get it right?
Yes. They got it right.
Georgia didn’t deserve to be in the playoff because they are a two-loss team. They lost to the two best teams they played, and one of those teams - LSU - beat them by three touchdowns. Bottom line - they lost. They had a 14-point lead over Alabama. They lost. Had they won, they would have been in. They lost. How some people (ESPN, perhaps?) can’t understand this is beyond me.
Ohio State lost. They lost badly to an unranked opponent 49-20 earlier in the season.
