I think I've spotted something that is driving sacks up and completions/yards per attempt down.
On Play action plays and/or plays where the QB is flushed out of the pocket he (QB) does not go wide enough and/or deep enough to give himself space to set his feet and throw. He will tuck in behind the Tackle thus immediately blocking out half the field, he then gets stuck and if he doesn't take off and scamper, he gets sacked.
By going wider and/or deeper he will give the play extra time to develop - which should lead to increased output on mid and long passes.
I've been looking at this as coverage sacks to this point, which they are (to a point) as the OL is doing it's job and the QB runs out of time. Here's some examples from my game in Victory today.
https://victory.myfootballnow.com/watch/558#101245This is a Singleback Normal Quick Slant play against a Nickel Normal Double WR3, he's flushed out but needs to be 2 yards deeper. However, rather than stepping back (and further across) he turns in towards the rusher. If he goes deeper and/or wider the play is extended and he can see more of the field.
https://victory.myfootballnow.com/watch/558#101280On this play, I formation Normal SE Post against 4-3 Under Double Safety Blitz. He feels the pressure moves out and immediately scampers for 10 yards but he was fortunate to avoid being sacked because again he stays too narrow. This time the blockers are able to do their job and he escapes. By going wider and/or deeper he gives himself time to survey his options before taking off, forcing the secondary to track receivers deep and giving him space to run into if no-one is open and he scrambles - it may ultimately lead to less yards on the scramble than he achieves here but it may also open up the deep ball throw.
https://victory.myfootballnow.com/watch/558#101265On this play, Split Backs 3 Wide Slot Post against Nickel 335 Cover 2 Man Under. This time it's just a 3 man rush, the OL are handling it but being forced back. Instead of stepping back and/or sideways he steps forward killing his time forcing him to throw the ball away, with the extra time from taking a step or two back the receiver he throws towards should be in a position where he's ready to receive the pass.
