idea to recruit measurables and try to find guys under the radar is a great philosophy for certain schools and it was not a horrible philosophy for Independent BYU, although they took it too far. It panned out for a lot of their recruits who became D1 contributors. Just can't build a whole roster that way.
The overly predictable Defensive scheme designed to sit back and wait for the Offense to make a mistake only works if you have far superior talent than the opponent, and if you have far superior talent every other style of defense that applies pressure with the front 7 works better. It is only good as a change up/situational D and those guys were running it as a base D. Not good.
