Since most nickel packages don't bother repping 2-back looks (simply because you'll be in base defense vs 21), a spread offense that lives in the 3x1 and 2x2 world can completely ham-fist the defensive personnel on the field when seeing power formations such as this.
Although an adaptation of the TFS since about 2007 (Brown/Black gun), the use of essentially 3-backs here by Louisiana Tech against a sound Utah State is exactly the same look they showed Mississippi State, with the exception of the tight end being replaced (and Franklin inserts a linebacker as a lead blocker).
It goes to show that everything is cyclical and if you stay in the same spot (schematically) all you become is a stationary target.
On a somewhat personal note, I find you can discover so much more about actual 'coaching' from the programs that have to fight for wins. It takes creativity, some guile, and a lot of hustle to manufacture plays that add up to wins when you're playing with a short deck. While Tony Franklin will never be considered a face for the public, there is no denying his commitment to his players and his humble desire to win. An interesting note to the season for La Tech is how much their offensive staff (in their first real season after recruiting) is relying on brand new faces to the program. With transfers (WR) Quinton Patton and (OT) Oscar Johnson, to true freshmen (QB) Nick Isham, (RB) Ray Holley and (RB) Hunter Lee getting the bulk of responsibility in the past four weeks.
