i did look up his OC stats for all his stops, including when he was a HC/OC. It hasnt really been favorable for him. Hasnt been bad either.
Norvs average ranking as OC or HC including his mega team the superbowl cowboys is 12 in points and 13 in yards. Take away his superbowl teams and walking into a good job with a top 5 offense 3 years running here and hes only had 2 other top 10 finishes in scoring or yards in 13 years.
and i also looked at passer rating for all the QBs hes "mentored" and posted that.
