There's another article from 2015 linked in the OP article where the schools are separated into two predicted tiers, though it doesn't really explain their method. Also, they're missing Duke, Eastern Michigan, Charlotte (soon to join FBS at the time of writing), and UAB (dropping FBS at the time), as well as Coastal Carolina and Liberty (neither FBS at the time). Duke is mentioned in the article as likely lower tier, and I assume the other 5 would be lower tier as well.
