Many of the heavy blitzing teams are in the AFC not NFC. So it is true that the Saints wouldn't have seen that much. There was a reason that we played preseason games against both the Ravens and Pittsburgh. But if you watch those teams you would see we are doing the same thing. Jim Johnson used to do it all the time using a 4-3 with Philadelphia. It isn't that unique but it is effective. It takes fast players who can get off the line and into coverage quickly backpedaling while watching their man. It seems to work better using man coverage because you are at the line with the offensive player and can focus on the player and move with him instead of defending a zone but we did it both ways.
Valid but he was available on a practice squad and not a sought after free agent for a reason. We must be careful not to back ourselves into a corner with this backfield situation. The run blocking is already not ideal and the reality is McCaffrey cannot be on the field all game every game if we want him to be available late in the season. Just like with Cam we must understand and adapt to the reality our best weapon is still human and other players have to help carry the load too.
