The G5 record is Marshall with 7 wins from 2009-2018. The P5 record is 11 with Florida State (1985-1995).

Ohio's 5 in a row isn't quite rarified air yet but its getting there. 6 in a row would be fairly rarified territory having been done only 9 times before.

Amount of teams historical bowl streak.

11 wins (1 team)
9 wins (2 teams)
8 wins (3 teams)
7 wins (6 teams)-Minnesota current
6 wins (9 teams)
5 wins (30 teams)

For the record Ohio St has never won more than 4 bowl games in a row. Cincinnati has never even won 4 in a row let alone 5.
