Fan exhaustion mixed with some satisfaction from cross-regional/national games played Wed thru Saturday will leave fan interest spent by Jan 1st.
In the old days the Sugar Bowl was New Year's Eve, pitting top teams from key conferences. Jan 1 a mid-day Cotton Bowl followed by the Rose Bowl, ending with the Orange Bowl. The matchups meant something given their representation.
Ratings are not going to be good for New Year's games this year. The others end Saturday, NFL takes over Sunday, and by Monday ...
Oh, and if you were a Horns fan in Dallas you went to a New Year's Eve dance the night before the bowl game, and if staying with classmates/friends played tag football New Year's Eve afternoon.
