OK then it goes to reason if FLorida beats OSU that that means they are a better team than Boise St since OSU is a better team than Boise St -- so why should Boise get a tie then?
You're missing the point. If Florida beats OSU, then there is only 1 team left with an undefeated record. The strength of schedule should be brought in as factor, only if 2 teams remain undefeated. OSU is only considered a "better" team than Boise State if they remain undefeated.
