This was a tough one, Stram built the offense that led to the 7-9 and 8-8 seasons, Nolan was not a good on the field coach, my dad said back then (and I agree) that if they would have stayed with Stram they would have made the playoffs in 78 and/or 79
I was watching games as an elementary school kid during the Nolan days and my pops also said that Stramm built that roster and then Nolan messed it up.
What made him especially mad is that Nolan was a former NFL DC and HC, before joining the Saints as LB coach, but his defenses as HC in NO were all-time bad. Man, my dad really disliked Nolan and so much so he didn’t like his son either.
