BPI has the shockers at #7 which IMO is closer to reality. They are a solid team with veteran and experienced players who haven't let a game slip against second rate competition. They haven't played enough tournament teams though to give them the clout needed for a 1 seed in my book. The committee shouldn't award them for playing a soft schedule and not losing, precisely the opposite: no 1 seed for super weak scheduling teams from horrible conferences regardless of record (set a precedent). Marshall needs to get off his high horse and play some road games at major schools if he wants to avoid this in the future.
Course they could do more, but they did play Tennessee, @ ALA, and @ SLU (a tourny team and 25-2), yes, the MVC isn't lights out but that noncon is at least something. They also got wins over a 2nd place BYU team and the first place team in the Southern in Davidson. Top flight noncon? No. Weak? Not too much, it is #34 noncon SOS according to ESPN. Other than playing one or two top RPI top 50 noncon I don't know what really more they could do. For reference K-State's non conference SOS is 148.
