On the heels of the road win at Syracuse, most of the tracking RPI sites have Villanova in the 9-11 range. These rankings fluctuate when 'Nova isn't playing because a team's RPI can change based on how their past opponents are playing.
Anyways here are some sites' RPI stats...
RealTimeRPI: #11 (doesn't have the Syracuse victory included at time of publishing)
