I think that the defensive scheme does a good job of masking weaknesses and allowing BYU to be successful and win games.

...And...

I think with more/more talented players and depth, the defensive scheme is capable of putting more pressure on the QB while also doing a better job of stopping the run - all while still protecting the back end and potentially being an elite defense.

I think what we've seen is Tuiaki making do with the players he's got to give BYU the best chance to win. Heck - even with Bronco it was interesting to see how much more blitzing he did after a few years of getting the right players into the program so that he felt like he could.

I know some will say that Tuiaki has had plenty of time - I'll stick by my original assertion that I like the trajectory - even though the climb might be slower than I want, BYU seems headed the right direction.
