Eric Mangini is planning on putting his own mark on the San Francisco 49ers' 3-4 defense with that being total confusion.
"All D-coordinators have their style," 49ers safety Antoine Bethea said, via peCSN Bay Area. "Coach Mangini, his thing is we're going to cause confusion. The opposing offense isn't going to know what we're going to be able to do each down. It could be bringing the pressure. It could be dropping eight into coverage. But it's just keeping the offense on their heels. However, you want to look at it, I think it's going to be a good deal for our defense."
Vic Fangio built one of the NFL's best defensive units from 2011 until 2014.
