Yes. And because our regular season schedule includes a bye in the last week of the regular season, we would end up with 2 bye weeks in a row. The FCS has 24 teams make the playoffs, top 8 get a bye the first round, bottom 16 play each other. Due to heavy regionalization (FCS playoffs are a money loser for the NCAA, so they try to operate as cheaply as possible) it rarely works out that the #9 team plays the #24 team. For example, right now several mock brackets have UND (11) playing at South Dakota State (15) in the first round.
I'd say around 15%.
