The Cowboys’ move to the 4-3 defense is music to Leon Lett’s ears. He’s going to get a chance to teach what he knows. “In a 3-4 you did more of a read-and-react. This is more of a react-on-the-run – rush the quarterback and then react to the run on the way to the quarterback,” he said last week as the Cowboys’ assistant coaches met with reporters. “Kind of the same thing I did as a football player, so I’m kind of used to it, and I’m looking forward to teaching it and coaching it." Lett collected 22.5 sacks and 229 tackles in a 10-year career with the Cowboys, twice making the Pro Bowl. He played at 6-foot-6, 290 pounds.
