I hear what you're saying, I've heard it said for years, but I don't buy most of it still.
I'm not at all taking away from anything Robin Selvig did, if you win 865 times at anything, that is special and you deserve the accolades, but if you can recruit black females to Moscow, Cheney and Laramie, you can get those same kids into Missoula and open the door.
When women's basketball in the NCAA was in its early years, I feel this was possible, if you gave the kid the opportunity the right one would take it. I am not convinced, as you suggest, anyone really tried too much. No one ever talked about it, it was all about getting the in-state players.
Note to football - winning the Montana recruiting battle could land you here

It just seemed like we had a pipeline that kept bringing the best two or three AA or A players and a bunch of 5'4" white girls. All in all, if you wanted to keep the team ivory soap, there were some scrappy white girls out there on those courts too I am sure that may not have gotten a lot of attention that nobody tried to recruit, but our team stuck to small town Washington for an out of state recruiting area. That's why we are where we are today and I don't see that we recover from that now. It was pretty obvious when you had a player with the talent of Karen Deden leave Missoula to go to Washington that that level of player wasn't going to play here.
