How Do I Stop Mesh Spot?

I keep on making it into the playoffs (H2H Seasons MVP division) but I always run into someone who keeps on using the same mesh spot play against me. Whenever I adjust to underneath he throws at the in route, and I’ve tried every formation from 5-2 to dollar to quarters to 3-4 to even 6-1. Any pointers? (I’m an 86 ovr nms)
