That does seem annoying, like people that Wildcat with Adrian Peterson. I like to run nickel packages against the Wildcat and blitz the corners with the rest of the defenders (save linemen) in zone. Simply playmake a couple of the zoners to blitz as well then take control of your safety. You will be ready to move to where you need to be for the run (usually outside) and if it is a pass or the QB back there you are able to make a play.
