Banker's scheme sucks. Flat out. It may work for Narduzzi, but Banker can't coach it and is too stubborn to do anything else. Also, Riley won't fire him, no matter how mad it gets.
Go look at Pitts D improvement under Narduzzi. In one year, its pretty remarkable and its in all categories.
Read about his quarters coverage. It looks nothing like what we play. He goes press about 90-95% of the time. To paraphrase a Pitt DB this year. "With no safety help, its the best man wins. The receiver has so many options so you get in his face and take away those options. Its physical. Its aggressive." This looks nothing like our D. 15 INTs to date. NU has had 5...... This is with team throwing like 40+ per game......
