RPI Does Not Make Sense

So, you think the BCS is bad? Try the RPI system for college basketball. Granted, RPI is not the only determining factor in a team's selection for the NCAA Tournament, but it's arguably the biggest. I don't have any stats or anything to back up my post about how poor of a system it is except for one. Maryland's RPI before their record-setting loss: 76. After they completely failed to show up for a rival game and were a 3-pointer away from being doubled: 68.
