As “bad” as it seemed, Joe Brady’s 2020 offense with Carolina averaged 349.50 per game - which is the highest YPG Carolina has had since Cam Newton was their QB.
And Kafka was the OC that got the Giants to the playoffs with Daniel Jones as his QB. I don't know that Kafka is the right guy, but he's certainly worth talking to and probably as worth talking to as Brady is. If for no other reason Kafka was actually on NFL teams for 5 years and has more years of experience as an NFL coach than Brady.
