Awesome, in-depth article on the origins / evolution of going deep and other similar routes in the passing game. Includes Spurrier, Favre, West Coast offensive concepts, and some Xs & Os talk. Something to keep this off-season from being so damn boring. Long read, but ton of interesting tidbits of knowledge:

"I have an admission to make: while I love a well executed power sweep or double-A gap blitz, and I'm a sucker for a well timed shallow cross or screen pass, and while I even get a little tingly when I see a run fit that stuffs a runner or when triple option quarterback fakes the pitch before cutting upfield, there is absolutely nothing nothing in football that I love more than a perfectly thrown deep post that hits a streaking receiver in stride for a touchdown. If there is one play one image that is totally unique to the sport, this is it: the play that would be illegal if not for the game's early rule changes to permit the forward pass; the play that would be unfathomable without the game's early innovators; the play that looks at the scrum at the line of scrimmage the part of the game most tied to football's past and essentially says, screw it, we'll just throw the ball over the top of all that. It is, in short, the play that makes the sport what it is."
