My rules as I stated in another thread are, minimally:I mean, if that was #14 Duke because it was a rival, fine.
For me, rushing the court is a "sacred honor." I'd say you have to beat a team ranked in the top 5 to rush the court if you are unranked. Top 2 if you are ranked outside of the Top 10.
a)top 5 team
b)big rival
c)big upset
d)win that puts you "over the top"(best example would be a win in football that you got into the Orange Bowl)
Obviously if Duke is having a bad year, it wouldn't qualify and likewise if your the #6 team beating the #5.
