There were samples this past week, but really I saw Dante going off the field and talking to a ref. Usually when a guy is going off on a ref his arms and head are flailing around and a helmet comes off and is thrown or the likes...I just saw him walking and talking....the ref IMO was BS. As far as the other issues like AD going off....well IMO it could very well have been a point where he was sick of the actions and crap of the hawks (taking on the persona of their HC IMO).
But overall I see no need to bring up questions about discipline unless of course you are talking about gap integrity....now there they have had issues and they do need to be addressed, and if not fixed at least improved on.
As far as the inside backers, well I think Littleton is holding up well...you get what you get with Barron...he is playing hard and he hits...
IMO the main issue with the D is in tackling, I have seen guys in spot behind the LOS and have a guy and the guy gets loose, and it goes from there...poor angles, grabbing at a guy.....If the tackling would improve you'd see huge improvement and less time for an O to get into rhythm.
Outside rush....IMO just improve overall tackles and that will come...keep gap integrity and the D will improve in all three parts...Backend, LB's and Line.
