Mike Gundy has a phenomenal knack for hiring offensive coordinators, so even if you haven't heard of Mike Yurcich, former offensive coordinator at D-2 Shippensburg, you can trust the hire simply based on those doing the hiring. (See: Holgorsen, Monken, and Fedora, to start.)
He also is happy to explain trick plays using Lego Star Wars figures. Our only complaint is the use of R2D2 as a center, a terrible call because he has no arms, and the absence of clear 5-star defensive end Chewbacca, aka "Jadeveon Clowney with a hair growth disorder." (via)
