Trust me when I tell you, it's really hard to coach around poor CB play.
If CB's are routinely losing their 1-on-1 situations then that's likely a talent issue.
And no matter how good the coaching is, kids will still get out there and do their own thing from time to time. Happens to all coaches. I know for a fact that Jackson doesn't teach that BS that we saw from our CB's on Saturday. Neither did Addae. I've watched both of them coach our CB's.
My biggest concern isn't the CB play though. I'm okay with our CB's getting beat from time-to-time IF EVERYTHING ELSE IS TIGHT. If a defense is really stout in between the hashes (i.e. good DL, LB and Safety play) and the offense HAS to go outside to generate any plays, that strategy is still LOW PERCENTAGE.
We're not giving up 30ppg simply because of our CB play. The issue is that our defense can't hang their hat on ANYTHING. They don't do anything particularly well.
