“With Kenny, there’s got to be a couple of punching bags in the weight room,” 49ers defensive coordinator Robert Saleh said over the phone.
“There’s got to be a speed bag in there. A lot of his drill work emphasizes quick, violent hands, bouncing, being light on your feet. Kyle will be thinking, ‘Are we teaching boxing or football?’”
Kyle is 49ers head coach Kyle Shanahan. And Kenny is Ken Norton Jr., the former Pro Bowl linebacker for the 49ers and Cowboys, the former defensive coordinator for the Raiders, the new assistant head coach/inside linebackers coach for the 49ers and the son of former heavyweight champion Ken Norton.
