Glad you brought that up. In addition to that Chin needs to teach his defense how to get off blocks, get in position to tackle, then how to properly tackle using basic head up, drive the shoulder and wrap with arms instead of diving at the ankles (while the ball carrier is in front of the defender) or the old grab them at the waist and spin them forward until they fall. Cornerbacks shouldn’t allow the receivers a free run off the line and turn your head at some point to find the ball. Safeties never let anyone behind you. Yes this is basic defense however Chin has seemed to have forgotten the basics, just sayin….
