The Amazon Prime analyst pointed the finger at offensive coordinator Kevin Patullo and sent a message to Nick Sirianni."When you look at this offense last year ... they were fantastic. you saw Saquon Barkley, offensive player of the year. You saw A.J. Brown have a great year, DeVonta Smith, great year. And then you inject Kevin Patullo as offensive coordinator and all of the sudden, these guys are suddenly struggling. And I think that's the issue."The Eagles rank 24th in the NFL in total offense this season, and nothing suggests that will change anytime soon.
