I've said often that Nebraska's biggest woes have nothing to do with the talent level. Nebraska's biggest problems are, as I see them:
1) the space between the players ears,
2) ridiculous schemes from previous coaching staffs (all previous three*, not singling out any one in particular) that set them up for failure, and
3) lack of "want", "passion", "fire", "emotion",--call it whatever you wish.
College football, even at the major P5 level is all about effort. Alabama, Ohio State, Clemson, Georgia, Oklahoma, all have great talent...but without the intense effort they put forth every game, they'd be no better, record wise, than Nebraska right now.
I think with Coach Frost, the numbered points I listed above will not only be addressed, but remedied. That's my hope anyway.
