I don’t think it was so much what the scheme and roster wasn’t, it was the lack of the adjustments. It was clear that teams watched film from previous games and concluded on “this down and distance they like to do this…”. Or “here is where teams so far have been able to attack them and find success… so we’re going to do that.”
The expectation is that our defense would do the same “let’s see what teams have been doing to be successful against us and what are we going to do to counter what we FULLY EXPECT THEM TO TRY AND DO…?!” No… we took the let’s just keep doing what we do and hope for the best route.
I.e.: Walking Kiko out wide to cover a RB. After the first game they should’ve been able to deduce that wasn’t the position to put him and find a better way to defend that.
Or how about having OJ and DPJ “follow” the best receiver when he’s on their side… nope. We’d do fairly well covering guys lined up outside against us and would let teams continuously exploit our weakest person in coverage on their best receiver because that some how made sense to Guidry. And Mario was complicit because he let him do it.
