In response to agcsbill's comment:
Why is it when a play "works" it is deemed a great call, but, when a play doesn't work, it is the OCs fault for making that call? Seems to me EVERY play that is called is expected to work if executed properly. Also, when a play is busted up and the offense turns it into a surprising gain, the "player" made a great play now! So which is it? A great call or a great effort by the player?
answer .... when a play catches the defense leaning a certain way and creates a big gain it is a great play call for the situation.
So, how can you call a play that will do this in advance? It appears to me this would occur when an audible is made.
conversely.... when a player gets sacked on a deep drop play action when the pass rushers appear to expect the play then it is a sh1tty call.
So... a good guess on the part of the D makes it a s**tty call?
also... when the offense throws a long incompletion on 1st down and a short completion on third down (3 and out ) early in the game... What does it say about the play calling ....????
Back to your first point, make a call that catches the D leaning a certain way. IE - 3rd and short and go for a long pass when the D expects a run.
Overall.. a guessing game on both sides of the ball. Some plays work and some don't.
