Real quick today, I offer an article from Matt Bowen of the National Football Post that analyzes an 85-yard touchdown pass from Arkansas QB Ryan Mallett.
As soon as you read the phrase "85-yard touchdown pass", you probably imagined a deep bomb to a streaking wide receiver who'd gotten behind the defense, right? Nope. This article is actually an excellent example of how arm strength isn't all about distance, but about velocity and zipping the ball to an underneath receiver before the defender can get there. It's a throw that college QB prospects are required to make if they want any respect from scouts, because it's a throw that NFL teams use all the time. This, and not this, is the definition of "beating safeties deep". A strong arm can split apart even a fast, disciplined defense.
Enjoy Bowen's breakdown. Be warned, it's heavy on the X's and O's.)
