Amazing the difference in these ranking sites. Most RPI sites have VCU’s SOS at 71, so I immediately jumped to the conclusion that you added a one by mistake.
The RPI SOS is all but meaningless at his time of year for a number of reasons, including the fact that it ignores margin of victory/defeat. Even at year-end, Pomeroy (or Sagarin and others) are FAR more accurate than RPI. Sagarin has the VCU SOS higher – #145 – because it puts more weight on opponents’ W-L pct as opposed to the quality of the opponents.
