Confidence is key. Not only in life but in Jeff Hafley's defense.
The Green Bay Packers' new defensive coordinator is working to implement that confidence within his unit now with a through understanding of its responsibilities.
"I want a defense that's going to be confident and that's not going to be nervous about making mistakes," Hafley said this offseason. "Play style is important to me and how fast we play and physical and attacking the ball and all that stuff, but the only way to do that is they've got to know what they're doing."
Hafley and his staff are in the early stages of implementing the system with their players.
