Defense makes quarterbacks. Quarterbacks who practice against good defenses succeed.
Most highly drafted quarterbacks end up on bad teams practicing against bad defenses. Their success in practice does not translate into success on Sunday. They lose confidence in the system, the coach, and themselves.
Joey Harrington is a prime example.
Now practicing against a good defense does not guarantee success Vince Young of the Titans comes to mind.
Yet many journeyman quarterbacks elevate their game just enough by practicing against a good defense to win Super Bowls, examples include Brad Johnson, Trent Dilfer, and Jeff Hoestetler.
Truly exceptional quarterbacks can develop without the benefit of practicing against a good defense, such as Dan marino, Bret Favre, and Peyton Manning.
So here is a formula for success. Take a quarterback, who has the physical and mental tools, one who has consistently faced or practiced against good defenses in college. Put that quarterback on a team with a good defense, then quarterback will develop.
So Detroit, my advice is to pass on a quarterback. Your defense was the worst in the league. Build a defense first or be prepared to repeat the Joey Harrington debacle
In the end, defense wins championships.
