this post kind of gave me an idea. what if pre-snap, you chose the progression that you want to look at your receivers in. so say you want to first look to x, then to b, then in the flat to black. at the line of scrimmage, you might hold the l-trigger to zoom back and see everyone... the icons for each receiver would pop up (without your primary one blinking. god do i hate that). then you press the buttons in order you want your progression.
when you then snap the ball, the cone (or maybe the icon of the receiver) is visible only above the receiver that's highlighted in your progression. to cycle through the progression, you might hit the l-trigger once to go to the next guy.
if you got to the end of your progression, THEN the cone would come up as it is now.
at any time WITHIN your progression, if you want to throw to a receiver that isn't in your focus, perhaps you still could, but with accuracy penalties. or you could maybe break your read progression at any time to get all of the icons to come up and have the cone as per usual.
what do you all think?
