Some quick research to illustrate the above point concerning the weak schedule ... There has been only one team since 2005 (most dated season I examined) in the RPI Top 50 at selection time that played fewer than three games vs. the RPI Top 50. That was #44 Texas A&M-Corpus Christi in 2005 with two such games (they did win one vs. the RPI Top 25). Every other team in the RPI Top 50 at selection time since 2005 played five or more games vs. the RPI Top 50.
