He portrayed himself as a football coach, and only had a handful of years coaching 8-man on the rez. Hell, it even got him an SI article, since Max didn't bother to vet him. A quick check on LinkedIn showed his inflated claims.
Which makes me skeptical when I see a person claim coaching experience in one post, but career military in another. I'm impressed that once you were finally back stateside you were able to land an assistant position at a major school in NY. Usually there's a chronological progression from other jobs to get that.
