Knowing the calls & reads is very important in his scheme. A missed read in this scheme can lead to big gains. That is why you will normaly see players who understand the scheme over players with natural talent. The key is to have your most talented players understand it & have the next in line learning it.
The problem with this is, the slow, nonathletic guys who supposedly "know the calls and reads" seem completely lost half the time.
I'd rather have superior athletes who are also lost half the time.
To say that the defense was lost lost half of the time is probably pretty far off. Don't get me wrong I'm not saying there was not times where the players were lost. College Football is just as much mental as it is physical. Throwing a young player into the lions den is not always a good idea. Osborne's teams rarly played a underclassman. Most of the defensive & offensive lineman were brought in kinda small & not ready to play. They would disapear for a couple seasons only to reapear larger & ready to go. High school football get these kids a lot more physically ready then they did back in those days & you will see more underclassman playing these days, but they are not all mentally ready to go. As far as skilled postions go NU plays a lot of their younger talent. ie Bell, Turner, Abdullah, Heard, Cross, Janovich, Burkhead & Martinez all played as FR/RS FR. I'm sure there are others but those are the ones off the top of my head.
