You may see some SEC at ACC home games, but I'll be surprised if any ACC game that doesn't also feature an SEC opponent ever makes it on ABC going forward (ACC championship game notwithstanding, of course.) They only have 3 time slots available on ABC every Saturday; they're not going to play some ACC snooze fest that nobody will watch like Boston College at SMU, even if it's a noon kick, and they're not going to play Clemson or FSU games when they could put Texas, Oklahoma, Tennessee, Florida, Alabama, Auburn, TAMU, Georgia, or whatever other SEC team on instead. Disney didn't lure Texas and Oklahoma away from the Big 12, then agree to pay the SEC basically double on their new contract, just to turn around and schedule ACC games in their OTA broadcast slots.
