Bronco didn't go to New Mexico to win football games. That would be crazy.
Bronco went to New Mexico to build men. OK, maybe that's crazy too. But as Bronco sees it, that is his purpose in life. Plus he can make millions of $ doing it and eventually buy a bigger ranch maybe. That's all secondary though.
Winning football games is just the cherry on top. It shows that he is successful at building men to the point where they can win football games. Overcome adversity. Play together as a team. All that good stuff. It's a measuring stick.
Looks like Bronco is already having some success at NM. Great.
