Well, Briles and Sumlin had a knack for finding guys with speed, Briles in particular. They both understood the disadvatantage of not reeling in big strong elite players and the need to offset them with speedy guys that could run circles around a defense, ANY defense. Much easier to recruit small speed guys.
Briles and Sumlin also understood the need to spread the field to take advantage of a much bigger defense. Just look at all the talent at schools
like UCLA, Texas, LSU, etc and ask yourself why they aren't winning championships. It's about understanding how to best utilize those talents. UH has talent, but we're not going to win many games playing smash mouth football and running a predictable offense, we're just not. It's going to take some creative innovative offense or a damn talented QB that can make up for shortcomings to really successful.
