I've only tested a the Dime Man. Seems just like a coverage 0 except the safeties don't come up to the LOS presnap. Only have a handful of plays with it's use so don't know if it's good or not yet.
I'm really intrigue by the "DE Contain". If you got one of those speed DE, must be great against those outside pitch. Of course you would have to know it's comming otherwise running right down the middle might be a problem.
