If your quarterback can’t deliver the ball to the open receiver, it doesn’t matter how well designed, well protected, or otherwise well executed your pass plays are. Surprisingly, however, this supposedly natural skill — the ability to locate and throw the ball to an open receiver — is taught in a variety of ways, some more effective than others. To my mind, there are really essentially two legitimate methods: the progression read and the coverage read. (The illegitimate way is to simply “scan” across — the most common tactic when a quarterback who gets in trouble — but this should never be taught to a young quarterback as an every down technique.)
Progression Reads: A progression read is designed to have two, three, four, or five sequential choices of where to throw the ball. It is important for the quarterback to pre-read the coverage to get an indication of the coverage, but, more importantly, a progression read requires the quarterback to know where each of the receivers will be given the pattern called. This kind of read calls for throwing the ball with rhythm drops — i.e. on a five-step drop, the ball is thrown to the first receiver when the fifth step hits (the “rhythm” throw), the second receiver after a hitch-up or gather step (the “read” or “gather” throw), and the third receiver after resetting the feet.
Limitations of progression reads:
- A tendency to stare at the receiver that is first in the progression, which attracts other defenders.
- It is frustrating for coaches to watch because they can see that a receiver who is later in the progression is wide open. Thus coaches need to know the progression as well as the quarterback — the QB’s job is to throw it to the first open receiver in the progression.
- Quarterbacks will lose patience or think that because the first receiver in the progression was thrown to the first time that he won’t be there when the play is called again. Progression reads require the coach/quarterback not have their mind made up ahead of time.
Coverage reads: The simple form of this requires that a pass concept be called and the quarterback is told to “throw it to this guy if the defender does this; throw it to that guy if the defender does that.” To make this work, the coaches and quarterback must understand the exact coverage called; there might be five receivers deployed but the coverage determines which two or three are “live” for the quarterback. In essence, the quarterback reads defenders, who dictate where the ball will go.
