The rash of injuries is trying to give him a pass. I just don't know if he is trying to cover / protect the younger players especially in the secondary or if they do not have enough time working together to execute complex defensive checks consistently. I just get the sense that he is trying to keep it all together with tape and hoping they can make it through the game.
The one thing that I do hold him on is the horrible tackling. That is fundamentals and needs to be addressed as a unit.
