Some Things To Look For In A Good Quarterback
Instinct
The QB must know who to throw to, given the defense or match-up. A good QB is also able to anticipate when to release the pass before the receiver makes his break. The 6th sense: Having the ability to sense pressure and avoid it while focusing downfield for intended receivers!
Vision
The ability to see the whole field on a given play and make all the appropriate throws in a given offense. This is much more important than being able to throw the football 60 yards.
Accuracy
Accuracy is more important than arm strength. If the offense is comprised of short to intermediate passes, the completion percentage should be around 60%. How many plays per game does a quarterback have to throw the ball more than 60 yards?
Footwork
Quick feet (which are very different from speed), agility and the ability to avoid rushers are very important.
Confidence
A good QB must have the desire to compete. When things are not going well, it is easy to place blame on the quarterback. The quarterback’s belief in his ability must be strong. The more sensitive he is to criticism, the less likely he is to succeed.
