Somebody MUST be accountable. In a normal championship level organization, Dennis Allen is responsible. His team should be free of dipsh*ts. So if you allow known dipsh*ts on the team, then you better have damn good discipline. Anyway, it's Dennis Allen should be fired. Not just for this incident, but this is just example A of the clown show he must be running down there.
As for Winston, I lost track. I think Winston came out and said he audibled (so blame him) and then said it was the team that decided (which is a BS cop out). But whatever the case, if the Saints want to say it's nobody's fault and that's the type of organization they are running, then they will most likely continue to be the same sputtering mess next year.
