Sean Payton’s crowd reception when he returns

Sean Payton was the architect behind our current hell. I'll be booing.
Why does Payton keep getting blamed? Loomis has continued to make the same terrible choices managing the cap, signing FA’s, trading picks, and drafting players for three years straight since the man left. Nothing has changed in those aspects. What exactly did Payton do that contributes to how the team looks three years AFTER he’s been gone?!?
