While getting into the backfield on running plays was great, Nkemdiche said he would like to improve at getting to the quarterback, working through the rush lanes.“Just playing with my hands and consistently doing what you’re asked on the defense,” he said. “Just playing more monotonous and doing the little things right.”Follow Adam Green on Twitter – / 31 Nkemdiche is a freaking beast, man pic.twitter.com/YL9HHjQ6ii— Billy Marshall (@BillyM_91) August 13, 2017Cardinals coach Bruce Arians said he could not give a full report or grade on linemen in the game, needing to check out the tape to get a true idea of how the guys in the trenches fared.Yet, he noticed Nkemdiche.“He was disruptive — I saw him in the backfield a few times,” Arians said.In the end, Nkemdiche was credited with three total tackles, solid numbers in a limited amount of work.Shoots the gap and the Cards hold the Raiders on 4th and 1.
