There is a play in the pistol called Y Cross Flood, if you send the WR ont he right hand side down field, the left receiver already goes down field, you get a touchdown around 90% of the time. Was playing a game online and got 11 TDs in onw game and almost 1000 passing yards in a game doing this. Clearly the down the field coverage is broken.
Its as if the corners and safties just flat out ignore the receivers. I noticed that anyone going down field in any formation can cause this to happen but in this playbook its almost always unless its man coverage..
