The FBS and FCS labels were adopted several years ago in an effort to placate some 1AA schools who didn't like the classification. But if you look at ESPN's website it includes the 1A and 1AA references in several places, such as schedules and standings. I haven't heard of any activist groups who've raised concerns with ESPN.
I'm with you, Pataskala.
Just like it was always Riverfront Stadium, where the Reds won the 1975, 1976, and 1990 World Series even after it was changed to Cinergy Field.
Just like it's always been Gund Arena that replaced Richfield Coliseum even after it was changed to Quicken Loans and then Rocket Mortgage.
I'm sure a lot of Cleveland baseball fans still call their stadium "The Jake" and will continue to use "Indians" and "the Tribe" even after the team's name is changed.
As for college football, the new classifications were meant to distinguish between 1AA's playoff system and 1A's BCS system. But the BCS system has morphed into a playoff, just with fewer teams, so the only real distinction is that a lot fewer 1A teams have a shot at a national championship compared to 1AA teams.
