So then read option is simply asking the QB to do more, make the call whereas a standard 'pro style' offense involves the OC calling the play and the QB sticking by that?
That's how I understood it - but does read option also involve the QB rushing more often? Presumably if they're unable to pick the play they're left with little option but to rush or be sacked or throw a silly int? I can't recall the game but I recall Cam throwing a rushed pass earlier in teh season that was easily picked and returned for a TD - a sign of poor utilisation of Read Option?
Put simply the option lets the QB key off of an indicator on the defense and make a decision on what to do with the ball based on what that defender is doing after the ball is snapped. For example the QB and a RB stretching left and the QB will either pitch to the RB or keep based on what he sees. On inside runs you see it where the QB puts the ball in the RB's belly then either lets him have it or pulls it back.
Yes running the option as your base offense requires the QB to run more and yes it puts them in harm's way more.
It does not work as well in the NFL as in college, for anything but a wrinkle to add to a traditional offense, because the defensive players in the NFL are bigger, faster, and generally smarter (in terms of football smarts).
