Here is the challenge, schedule-wise. If we stayed in the AAC for the next 5 years these would be our "marquee" games:
Illinois
Indiana
UCF
Houston
Memphis
Temple
Navy
Purdue
Clemson
NC State
Duke
Boston College
Going independent doesn't really change that list as you can replace UCF/Hou/Mem/Temple/Navy with almost any viable FBS program, Air Force, Wake, Marshall, Buffalo, really any MAC/CUSA schools and low-mid tier P5.
Looking at the OOC list, it seems the AD has been planning for this as a possibility. Games like UMass will always be there, and BC/Cuse/RU/Pitt would be likely willing to swap games every few years. 2023 has three P5 games signed already Duke, NC State, BC. It will be tough to fill out 2020 and 2021. Be prepared for 5/6 home games and games against whomever is available. 2019 is not 2012 or even 2017. The AAC media deal would be a quick death. We are still screwed, but I like that the AD is taking some initiative on this.
The effect on bowl access and recruiting are the negatives. I don't think the losing the AAC schedule matters a whole lot in 2019. We all hated it anyway. Games will be on SNY or some other outlet.
