Relying/depending on big plays to win is not a reliable way to do it.....And poor OL or not, no counters for a D that's confusing them and the QB is a recipe for disaster.How to win... As Scott Frost said, we need to rely on big plays on offense from our speed players. With our poor offensive line play, we will not sustain many long drives.
As to mindset. It can't be taught.....You can teach mechanics, you can teach fundamentals, scheme, game plan etc, but at the end of the day you can't teach that killer instinct. "Everyone wants to be a lion, until it's time to do lion sh!t"......You find lions and teach the rest. That's the way to flip the culture/mindset/killer instinct etc....Just my .02.....
