We'll need 6 wins. Even with 6 wins, it's not a 100% guaranteed that we would get a bowl invitation. Temple was 6-6 last year and did not get invited...probably for two reasons: they have a VERY poor reputation for fan support (i.e. can't sell tickets) and they finished the year 1-4 (their win was an unimpressive 10-3 game against Tulane).
Our 6-6 would be different because, to get there, we will have to finish the season stronger than 1-4. We will have had to beaten ECU (Check!) and one of the ranked teams left on our schedule, in addition to Tulane. And while our attendance hasn't been exceptional this season, it has gotten slightly better until last night. We've sold bowl tickets before and would have a better reputation than Temple last year to do it again.
