He left a single safety between a receiver and the goal line with 10 seconds to play. He rushed 4. He had LBs playing within 7-8 yards of line. He had guys peel off with shorter receivers and he left a notoriously bad tackler one on one on the one guy that could beat you. It’s similar to today. He created the UNNECESSARY circumstance that allowed an opponent to beat you. His defenses give up points at ends of halfs game after game. In close NFL games that’s a big deal. And it’s those circumstances that keep him around .500 as a coach. He can coach exactly the same way but If he learned from his past mistakes in those 2 minute situations he’d be awesome. Always man to man in 3rd and long late allow for big plays.
