How to stop short spam passes to outside

I feel like 50% of people on Super Bowl run repeat 2 plays 1 being a quick pass to the outside for 5 yards or corner route not really sure how to stop those plays I assume they must not be able to be stopped unless you dedicate the user and leave other things open

From what I understand you can only consistently stop corners with 25-30 yard flat zones on the outside corners and safeties only. 
 

I usually set that up on the side with the extra receivers that have corner route potential.

I have been putting the purple zones to five yards and they seem to play similar to a five yard flats.

I mix in man and purple zone flats to stop the short outside stuff while being able to have the 30 yard blue flat on the field.
