I missed this when it was written, but a good profile on him.
Sperber left a staff position at New Mexico State to make a bet on himself. Now his site is drawing lots of attention from fans, coaches.
theathletic.com

Honestly, I consider him a bit of a kindred spirit. I entered that same TeamRankings competition years back (my entry was... worse lol).
