Waco my first 2 years out of College 1976-78, I coached at TN High. Yep, Darrell Watson was there. He was magic. His unique ability was to simplify. We liked each other and I highly respected him as a man and coach. He told me that if I stayed in the business I would probably be a defensive line and Linebacker coach. He gave me 4 things for winning upfront. Good stance, control gaps, good hands and wrap up. Of course it was more complicated than that, But if you don’t do those things all the sets and stunts in the world are meaningless.
