I wonder if this is a function of the BIG people on the committee keeping UNC low enough that a win by UNC over Clemson knocks Clemson out of the playoff but keeps UNC far enough away that it is easy to put both the winner of Iowa/MSU and Ohio St. in the playoff.
Then again, UNC did have a pretty poor strength of schedule this year.
