I enjoy watching Green Bay, however, I must condone that some things (even the obvious) can easily be missed. A great example is that of your average diver. Do you think they constantly monitor what's happening behind them, what's happening beside them, what's happening in front of them, all while ensuring the needle stays at or below the speed limit? To top it off, how many people do that while checking both ways when passing through intersections and constantly making plans in case someone around them makes a huge mistake? Even if you do perform such actions, eventually you won't check an intersection for traffic, make a plan of action, or will inadvertently drive a few mph over the limit because you forgot to glance at the speedometer.
These things happen, one can only hope the referees learn from their previous mistakes.
