https://www.espn.com/college-football/insider/story/_/id/... G5 schools were broken down into five tiers. Ohio was put in the third tier, which was described as "some resource or location limitations but enough to make bowl games consistently and challenge for conference titles; a restricted but decent recruiting pool of regional or national prospects; a rare New Year's Six appearance is the ceiling; not a realistic candidate for Power 5 expansion."
Sounds accurate. Half of the MAC is in the third tier. Aside from Ohio, there is Central Michigan, Miami, Northern Illinois, Toledo and Western Western Michigan. The fourth tier includes just Bowling Green and Buffalo. The bottom tier is Akron, Ball State, Eastern Michigan and Kent State.
The top tier included only Boise State, Cincinnati, Houston and UCF. The second tier was a little bigger with BYU, Memphis, Navy, San Diego State, SMU, South Florida and Temple.
The third tier is big and includes Air Force, Appalachian State, Arkansas State, Central Michigan, Colorado State, East Carolina, Florida Atlantic, Fresno State, Georgia Southern, Louisiana, Louisiana Tech, Marshall, Miami (Ohio), Northern Illinois, North Texas, Ohio, Southern Miss, Toledo, Western Michigan and Wyoming.
The fourth tier also is pretty big and includes Army, Bowling Green, Buffalo, Charlotte, Florida International, Georgia State, Hawaii, Liberty, Middle Tennessee, Nevada, New Mexico, Old Dominion, Troy, Tulane, Tulsa, UAB, UConn, UNLV, Utah State and Western Kentucky.
Finally, the fifth tier is Akron, Ball State, Coastal Carolina, Eastern Michigan, Kent State, Louisiana-Monroe, New Mexico State, Rice, San Jose State, South Alabama, Texas State, UMass, UTEP and UTSA.
