Okay, I haven't been one to come on here and call out the coaches, but here you go...
There are a lot of coaches in a lot of sports who get caught up in a "scheme" and aren't flexible about it. Greg Williams at Texas was caught up in his scheme until VY walked into his ofice and made him change it. Landry was caught up in the Flex defense and refused to budge until the rest of the league had passed him by.
Defensively, our coaches are addicted to the 4-3. They absolutely refuse to play a nickel package. They refuse to adjust to the "new" version of football, where everyone plays a spread offense and you have to play 5 DBs in order to compete defensively. Yes, they have budged a little bit, and switch ocasionally to a 3-4 (more effective because the safties can give the corners deep cover and allows them to press more, whereas in the 4-3 zone, the safties have deep middle responsibility, don't provide protection on the outside, and the corners other than McCann have to give a 15 yard cushion). But never, ever a nickel. If we played a nickel, we would be adding speed to the secondary and taking our least athletic player, Bonilla, off the field. This is a fundamental flaw. Anyone who goes to our spring games and watches our own spread march up and down against the 4-3 man-zone has see these types of defensive performances before.
Offensively, we are stuck in the spread. We have great TEs. They block fantastically. We have a RB who got 7 yards every time he touches the ball, and he is huge. Just use the guy. Mix the formations up a bit and use him. Please.
A "multiple" offense and a "multiple" defense implies that you change schemes. We haven't been "multiple" for years, regardless of what the coaches tell us at press conferences.
