What does this mean for a QB playing well? Look at a typical offensive play, and let's forget performing well "under pressure", almost every QB falls apart when a NFL caliber DE is up his backside.Walking up to the o-line to get under center, the QB has to check to see where the middle linebacker is so he can identify what the base defense "might be" for the o-line to make their blocking calls.Then he checks both safeties for a cover-1, -2, -3 look. Then the experienced QB's will check the depth that the cornerback have taken to identify man to man, press coverage or zone.The best QB's can check the distance that the DE has between himself and the DT, if it is a 4-3 to tell him if they are playing run, if they play on rushing the QB, or even for a zone blitz look.All of this and more is required of a QB while he still has to call the play, make adjustments, and get his RB's, TE's, and WR's in position. There are so many tells that a defense can give to a very experienced QB and O-coordinator, that's why we see Peyton looking at the pictures on the sideline like a 13 year old looking at his first Playboy.Now throw in 3-4's, combo looks, a 4-2-5 and we get to see how well a QB can trust his preparation and film study, process all of this very quickly, and then do the most important part for a QB (at least mentally)...quit thinking and trust your instincts. Their insticts are honed in practice, film study, and game play. The great ones have it and with coaching and playing time come to rely on it. This is why I love watching Favre play...he may have the best instincts and feel for a game of any player ever, and he is usually right, but when he is wrong...watch out.The Wonderlic can provide a team an idea on how quickly a QB processes simple information. Great for Akili Smith and Joey Harrington, unfortunately they couldn't get their heads out of the way to play the game naturally. Anyone who watches the CBS show gets the sense that Marino is on the wrong side of most jokes and doesn't even get it, but that vacuum inside of his head allowed him to play football with the prettiest release ever.A true test for a player that plays with good instincts and has a natural feel for the position is the 2 minute drill. The great ones execute it like they are the only ones playing the game and that to me is a HUGE determining factor.
