It’s quite simple…

– 18 parts offensive rebounds for the 7-seed

– 19 parts total rebounds for the 2-seed

– 5/22 parts shooting from 3-point range for the 2-seed

– ratio of 6:13 parts assists to turnovers for the 2-seed

Mix all of these together, then do your best to give up a triple-double to the 7-seed’s back-up point guard.  That should set you up quite nicely for the upset.  Perhaps even one that’s out of hand in the final 2 minutes.
