A few things that I like to do when I'm playing someone who is nanoing alot.
-Figure out where the pressure is coming from is key to finding ways to exploit the play.
-Having a good sense of playing calling when you figure out where the pressure is coming from. Also, a good way to avoid nanos and making whoever your playing switch it up is to
use motion, quick passes, hitting the flats, finding a solid run and pound the ball, finding a play that is just killing him and running hurry up and making him play your game.
-Slid protecting (I've noticed that sometime it stop some heat, or at least give you more time in the pocket.)
-And F@G offense, if he's just killing you, by any means do what you got to do.
Just a few helpful tips.
