Not if you are suggesting that your 'gunners' on the punt coverage team who are running down the field at fulll speed are supposed to be watching a ball that is 90 feet in the air and behind them...while trying to fight off and shed the 'jammers' on the other team...while trying to track and time arriving at the returner as quickly as possible...either before the ball arrives forcing the fair catch or right after the ball dropping from the sky does so they can make the tackle as quickly as possible. I would hate to see the absolutely crushing blows these guys would eat on every punt if they were being asked to 'Keep their eyes on the damn ball'. Everyone else is required to wait until the ball is kicked so they don't usually have that problem. Some of them will certainly be able to get a glimpse of the ball and its direction/trajectory but keeping their eye on the ball isn't the main objective...they are supposed to be maintaining their lanes while fighting off blockers while converging on the returner.I dunno. I have had a good bit of experience screaming things like "Keep your eye on the damn ball!"
Does that count?
