A complete zone D with the patches in this game is broken. DBs seem to run the opposite of where they should or not even pay attention to where a WR is running.
You may want to call a D that is man but with some zone coverages (there are alot of options in the 3-3-5). Also Cover 2 is a good option for 3rd and deep.
For me, I rarely ever move my coverage in. I leave the DB's as they are and dont jam becauase my DBs arent good at it and it has worked out for me so far.
Unfortunatly, the only DBs worth recruitng in this game, are ones that are good at man coverage
