Sam Bradford's Performance Shows He's a Perfect Fit in Chip Kelly's System

In his first opportunity to experience extended action as a member of the Philadelphia Eagles, quarterback Sam Bradford showed exactly why head coach Chip Kelly decided to trade Nick Foles for the former No. 1 pick. 

Bradford is an ideal fit in Kelly's offensive system. 

When the mad scientist made the leap from the collegiate ranks to the NFL, his high-octane offense was mischaracterized as needing a mobile quarterback to run properly. 

Nothing could have been further from the truth. 

Quarterback play in Kelly's offense is predicated on decision-making and getting the ball out quickly and accurately in order for the receivers to create after the catch. These two traits once made Bradford a Heisman Trophy winner. 

At Oklahoma, Bradford operated one of the fastest and most explosive offenses college football ever experienced. During his historic 2008 campaign, the quarterback from Oklahoma City completed 67.9 percent of his passes for 4,720 yards, 50 touchdowns and only eight interceptions. 

The Sooners excelled, because the coaching staff allowed Bradford to become the offense's maestro. As plays were called in on the fly, the quarterback orchestrated the scheme to perfection due to his precision and uncanny accuracy, which elevated the play of those around him. These traits eventually made Bradford the St. Louis Rams' No. 1 overall pick in the 2010 NFL draft. 

The Rams organization failed, despite the quarterback winning the 2010 NFL Rookie of the Year, by playing Bradford in a traditional West Coast offense that didn't suit his strengths. The Oklahoma product was no longer in a wide-open offense where he could pick apart defenses after spreading them out from sideline to sideline. Instead, everything became condensed. And Bradford never developed at the expected rate. 

St. Louis also failed to properly place weapons around the former top pick. 

Neither of these will be problems in Philadelphia.

Does Kelly prefer a mobile quarterback? Sure. But mobility remains a distant second to the signal-caller's ability to sling the football.  

"In a quarterback, I look for a quarterback who can run and not a running back who can throw," Kelly said in 2013, per Philly.com's Rich Hofmann. "I want the quarterback who can beat you with his arm. If the defense forces him to run, he can do it effectively."

The coach wants what every coach wants: a complete quarterback. The zone read, however, is merely an extension of the scheme's running game. It doesn't set up the entire offense. 

Tempo and getting the ball out quickly are the preeminent thoughts in Kelly's mind when picturing the perfect quarterback running his system:

"

The job of a quarterback is simple. He has to "let it happen, and not make it happen." We want to move forward. That is a concept you have to make your team understand. The cardinal sin at our place is the quarterback sack.

We want the ball out of the quarterback's hands in 1.5 seconds. That does not mean holding the ball until 2.5, waiting for someone to get open.

"

This is where Bradford excels. During his first road action since tearing an ACL for the second straight season, the quarterback looked far more like the one seen at Oklahoma than the version who struggled to establish himself in St. Louis. 

Philadelphia's new gunslinger finished his night 10-of-10 passing for 121 yards and three touchdowns against the Green Bay Packers. Disney couldn't have scripted a better return for a player who suffered through two years of devastating knee injuries and rehabilitation. 

Preseason games generally don't mean much, but Bradford's perfect performance certainly ignited sparks of hope within the Eagles fanbase. And it should. 

With one performance, Bradford went from an injury-prone quarterback who required bubble wrap to make it through a season to the signal-caller who can make Kelly's explosive offense even more dangerous. 

Below is a video compilation, courtesy of YouTube, that highlights each of Bradford's throws in Green Bay: 

What became immediately clear in watching each of the throws is the rhythm in which the quarterback played. 

In almost every instance, Bradford hit his back foot, made the proper read and uncorked a pass for another completion. There weren't any unnecessary hitches in his footwork or doubt where the ball should be thrown. The quarterback simply let it fly, and the offense couldn't have looked any better with three first-half touchdowns. 

Two of those touchdowns stand out based on what the quarterback accomplished. 

The first touchdown, provided by Bleeding Green Nation, was a wonderful example of proper recognition:

As seen in the video, Bradford immediately recognized a mismatch. While all the receivers were covered during the routes, the quarterback found running back Darren Sproles for the touchdown toss. 

No linebacker in the NFL can cover Sproles out of the backfield one-on-one. As soon as Bradford identified man coverage on the running back, he made the right decision and a perfect pass for an easy touchdown. 

The second touchdown, courtesy of Inside the Iggles' Anthony DiBona, displayed Bradford's ability to compensate for his lack of mobility in and around the pocket: 

A quick release and quicker decisions can neutralize a defense's blitz. Inevitably, teams will get pressure on Bradford, and the quarterback isn't going to make many defenders miss. Getting the ball out quickly without taking big hits will negate the pressure to a large degree. 

In the above case, Bradford saw the oncoming pressure, stayed in the pocket and still delivered a perfect pass for the team's second touchdown of the evening. 

Health, particularly if teams start to get more pressure on the quarterback, remains a concern. It will until Bradford proves he can play an entire season again. 

Until he actually does or doesn't, the Eagles shouldn't worry too much about the quarterback's ability to lead the offense and take it to new heights. 

Bradford can do the two things Kelly wants most from the position: He can beat you with his arm, and he gets the ball out quickly. This is all that's required to operate the NFL's fastest offense, and Bradford remains the perfect pick to do so.
