I also see a lot of this from Manny’s defenses like when he was fired:
“One of the biggest problems against BYU - in addition to Diaz basically playing a 4-2-5 scheme (this is what Texas opened in) and even a 5-1-5 scheme - was that the defensive line continued to shoot gaps instead of a base, read-and-react, gap control defense.
So when BYU would slant its offensive line to the left or right, and the Cougars did that a lot, it allowed BYU to get the Texas front flowing in one direction. Then, BYU would counter or cut back with Hill or a running back in the opposite direction with nothing but open field.
This is the same stuff that got Diaz's D in trouble last year. His D-linemen needed to hold their ground, engage blocks and shed blocks to protect their gaps. Instead, they were out of position all night.”
His defenses, particularly his DLs, play undisciplined style football with no gap control. However not to be outdone his secondary can often suck as well. Wisky’s Hornibrook (who couldn’t even keep his starting job and was forced to transfer) was the OB MVP. That night he looked like he was ready to be the #1 NFL pick. Once teams adjust during games Manny typically has no answers or strategy.
