I'm reminded of something a former football coach told me, "you can't win with just Idaho kids." (and no it wasn't John Zamberlin - who had a number of local / Idaho kids on his rosters)
Balance is the key to anything. Sure you want some Idaho / area kids on the team whatever sport but the basic question has to be, can they actually play at that level?
If you think they can, you recruit them and try to get some, but you can't focus exclusively on them and you can't just listen to fans / supporters who say to recruit local kids in essence just because they are local.
Winning is the bottom line, that's solves most problems including where your recruits are from.
A few more thoughts on this in no particular order.
Remember it takes two to tango. I know a number of times when ISU coaches were recruiting local / area players who simply had little or no interest in the Bengals. It happens. Doesn't mean the kids are "bad", doesn't mean the coaches are "bad." It just wasn't a match. The player has to be happy and comfortable in where they go, that's another bottom line. They are the ones having to go out and play...not the parents, not the family friends, not the boosters.
Remember ISU is also in competition with schools in the Salt Lake area, with BYU and with Idaho and Boise State for players. They aren't in a vacuum. Everyone knows what BSU has done in football for the past 10 years but now the men's basketball team is stepping up. They'll be ranked in the Top 25 next year, they played at Michigan State last year...they play at Kentucky this year. That is appealing to kids. Facilities also play a factor, sometimes a big one. I know for a fact that ISU lost players to another state program because it came down to facilities. Why do you think Jeff and his staff have worked so hard on improvements in this area over the past five years? It all factors in.
When the ISU women's basketball team won both the regular season and post season tournament title in the Big Sky 14 months ago, they had one player from the area / state (Sheryl Bitter) on the team. Did that fact damper the enthusiasm for the club by ISU fans? No. Like I said, if you play hard, give good effort, conduct yourself in a reasonable manner on and off the court, go to class and win fans honestly don't care where you are from in my opinion.
