Doesn't mean 4-3 personnel or even that alignment. Remember McCarthy also said they had plans for different packages that went by the wayside when Jones and then Matthews got hurt.

McCarthy is saying you can't not use what you have on the sideline even if someone is injured. So if you had a plan for Psycho with Jones and Matthews rushing from the same side, you can't stop using that D if Matthews is hurt. Injuries cannot make you be simple. Mostly because the Packers rarely are assignment sure when young.
