re: Mett and reading defenses...many of you have mentioned that he has

Reading defenses means, looking at where the defenders are lining up and using that information to guess what defense they are playing. An example of this would be if their defenders are lining up directly in front of you receivers and backs, they are "manning up," or more than likely playing "Man-to-Man." Another would be if their "Safeties," or two deepest defenders, are dividing the field in half, then they are most likely in some sort of "two deep" defense. It would be a two deep zone if their defenders are not lined up in front of your receivers and appear to be prepared to guard an area.

Quarterbacks need to know this, so they have a reasonable chance of running a successful play.
