I have been fascinated with the quarterback controversy that plagued BYU this season between the hyped phenom Jake Heaps and the grizzly "gamer" Riley Nelson. While Nelson had much better traditional statistics than Heaps, Heaps played against a tougher schedule. The author of a the BYU sports blog LoyalCougars.com asked me if it were possible to statistically correct for the difficulty of the defenses Heaps and Nelson played to compare them on level ground. Being a football fan and a math nerd, I dove right in. The results are written up in a post over at LoyalCougars.com, so if you feel like delving into the statistical rabbit hole, go check it out.
