Anyone not a fan of the offense looking to the sideline to make audibles. I would rather my QB make adjustments as he sees it. It also gives the defense a chance to audible too when they see the offense looking over to change something. I watch most top QBs ( bridgewater, McCarron, mariota, maziel, ect...) they all audible at the line of scrimmage and not look over to the OC to change things.
