I wouldn't either, but the article suggests there is appetite from a TV viewership standpoint for a few more (as many as 5), though it didn't suggest there will be any expansion.
Whether it can be figured out how to keep the existing ones financially solvent relying on much less adding others is a different matter.
Conference tie ins might dissolve or be altered significantly is one suggestion, allowing Bowls to go for more regional matchups and help with costs.,
Just me speculating, maybe some are held on campus, cutting travel expenses at least in half. Maybe multiple bowls take place at the same site or even the same date.
TV viewers don't seem to care about the quality, they just want more college football to watch. I can't explain why, it just is.
