AAC is on ABC.
How many TV packages have ESPN that don't have ESPN2? That would be none since a carrier must have both to get either.
And the correct ESPN college football hierarchy is...
ESPN
ESPN2/ABC
ESPNU
ESPN News
Watch ESPN
ABC isn't over ESPN since ABC has only 3 bowl games that all conflict with times of games on ESPN. And ABC does not carry playoff games. ESPN2 carries more Saturday games than ABC. ESPN2 only has one bowl game since it is used for counter-programming against bowl games.
ESPN Classic carries no live events, so it isn't even on the radar.
