It's not just that NYD (or the day after in this case) isn't as important as it used to be-- it's also that every weekend during the college football season now has games from 11 AM to 2 AM. That wasn't true 30 years ago.
NYD always felt more special, because there was simply MORE football being played, all day long. Now, even if every game were on a different channel and not ESPN, there'd still be less to watch, than any average Saturday in the Fall.
