I did not play football when I was younger (although I wanted to but didn't meet the weight requirements). For those of you that have football experience and have played in zone defense before please answer this question: Is zone defense supposed to be played the way the Steelers are right now?

It seems strange to me that a defense was devised to allow a receiver to catch a pass with no one within 5 yards of him.

The reason I ask is if they are doing it wrong why haven't the done anything to correct it?
