You may be thinking of the old A-10, before Xavier, Temple, Butler and Charlotte left. The current A-10 roster of 14 teams is bloated with some sorry programs right now, according to KenPom. Almost 2/3rds of their teams this year sport a triple-digit KenPom rating.
Dayton - #39 KenPom
Rhode Island - 49
VCU - 51
Davidson - 91
St. Bonaventure - 92
LaSalle - 102
Massachusetts -113
George Mason - 119
Richmond - 120
St. Joe - 128
GW - 170
Fordham - 204
Duquesne - 223
St. Louis - 310
Now the MVC is in the same boat, with 70% of their members having a 3-digit KenPom rating. But their top two teams are higher than the A-10's, though the 9th and 10th teams in the A-10 rate higher than the same in the MVC.
Wichita St. - #22 KenPom
Illinois St. - 34
Loyola - 95
Missouri St. - 117
Northern Iowa - 155
Evansville - 157
SIU - 166
Indiana St. - 196
Drake - 217
Bradley - 235
Bottom line, both coaches are big fishes in a small pond and unless they can elevate into the Big East, like other similar basketball-only schools did (Xavier and Butler), they're going to be relegated to fighting for their conferences' 1-2 NCAA berths each year.
So in Archie's case, why not consider a hefty pay raise to coach in one of the most prestigious conferences, where 6-7 schools per year get into the Dance and often are legit title contenders.
And while Marshall already makes some serious coin, is it realistic that he catches lightning in a bottle twice at WSU? Under-rated guys like VanVleet, Baker, and Early were probably generational players there and to have three like that at the same time isn't likely to happen again.
