You can't just manufacture good matchups. ESPN is at the discretion of the committee.
You're not going to avoid the NFL, especially if you expand, unless you get rid of conference championship games (very unlikely) or move up the entire calendar (very unlikely). So what you're left with is staggering games (similar to the tournament) or having a triple header on Friday. Is a game like Boise State vs. Miami starting at Noon on a Friday, followed by Bama vs. ASU at 4 going to move the needle enough to warrant to pay another $230ish million. I'd say no, but if ESPN is fine losing money with this, just to have it, then that's fine.
