I agree with some, but not all of this.
1) They follow the rules as currently in place. You can't complain, because anybody could do what they do if they wanted. There are plenty of schools that recruit older foreign athletes.
2) The Utah high school scene has been amazing the last 5 years, but BYU has been a top program for a lot longer than that. Having a 'Mormon Monopoly' certainly helps, but other schools like Stanford have similar advantages because of their academic reputations.
3) BYU is only in the WCC because nobody else will take them. They are subject to the demands of their Independent football team. Anybody who follows NCAA conferences understands this.
4) BYU uses those altitude conversions pretty rarely, maybe one or two guys per year take advantage of that. The conversion definitely helps, especially in the 1500/steeple, but any school who wants to can use those same conversions.
I do agree that the BYU team needs some humbling. Specifically Linkletter talks a big talk, and then he doesn't usually back it up when it counts. I have heard that he really butted heads with some of the upperclassmen when he first showed up at BYU because of his attitude. He is a major contrast from somebody like Jared Ward, who is as humble and easy going as they come.
Regardless, Eyestone has to change something. His teams have underperformed at so many national meets recently that nobody takes them seriously anymore.
