Who we went undefeated against is the problem.
The system is rigged to favor those who play in very strong conferences. Relative to most conferences, the Sun Belt benefits from the way RPI is "rigged". The problem for the Cajuns this weekend wasn't The RPI of their opponents as much as it was the fact that both had very poor records. As of today, SFA is 5-20 and UCA is 8-15, playing each twice added 26 wins and 70 losses to the "Opponents' record" portion of out RPI. By way of comparison, the two worst RPI among our Conference opponents are a combined 22-22, even though both have RPI's similar to SFA. Since Opponents' record is 50% of RPI, it is pretty easy to see that our weak conference opponents do not hurt us nearly as much as UCA and SFA did.
