I think passing is going to be more difficult. The number of zone concepts in the game looks like it's going to increase greatly, and they are employing pattern matching principles that are getting stock defenses to shut down routes that were incredibly hard to guard in M18. I started a thread for it, but I link here as well.

Apparently there are now various pattern matching calls for cover 3 and cover 4 so things like verts and corner strike can be shut down by stock plays.
I've also seen, in a different video, a stock 2 man under shut down a mesh concept with the right WR on a corner route, so drags and corners aren't auto-wins vs. M2M any more.
