...to be an awful tactic, "Bend but don't break." Except, in the end BYU's defense broke and Houston turned a 9 minute beat down into 6 more points. Honestly at that point I thought BYU was cooked. The reason BYU won was altitude conditioning. The same drive wore out Houston while BYU was strong enough to get a second wind in the 4th quarter. Of course the scheme change was huge as well. Rushing 4 full sized 270-300 lbs D Lineman was too much for Houston's tackles to deal with and BYU started disrupting Tune's game.
