Some coaches think they know everything, but they really don't. They tell you what they think is best, but it's really what's best for them.
I see more now. As far as concepts, I know where teammates are going, linemen are going. I can read defensive fronts. I can read the body language of linebackers. I study film to see who's a bull rusher and who's a finesse rusher. I think I've learned.
