Christian Ponder Must Show More Confidence in his Arm
That kind of confidence and trust in his arm is something Christian Ponder certainly lacks. A missed opportunity from the Vikings' Week 17 game against the Packers perfectly illustrates the point.
Ponder faces a 3rd-and-4 at Green Bay's 19-yard line. His target will be Jarius Wright, who will break to the corner from the slot.

As Ponder prepares to release the ball, he makes two key mistakes.
The first is that his feet are parallel and one is not firmly set. So he is unable to step into the throw and put some velocity into it.

Two key points of Ponder's mechanics are wrong.

The second mistake is that his wind up is too long. Ponder is throwing from a high, head-height release, instead of bringing the ball up as he turns his hips in the direction of the pass.
He is almost flicking the ball, rather than launching it. This means the trajectory of the pass will always be downwards.
Ponder could have avoided these issues if he had the confidence to step up into the clean pocket in front of him. He has the room to lean into the pass more.

The ball should lead the receiver to the end zone.

Ponder's hesitancy botches a simple touchdown.

Because he was not more physically assertive in the pocket, Ponder missed a chance to complete a simple touchdown pass.
A weak arm has been a criticism of Ponder during two pro seasons. In 26 starts, he has averaged just [You must be registered and logged in to see this link.], according to NFL.com.
On this play against Packers, he certainly looked like a quarterback who does not completely trust his arm to make all the throws.
Of course, refined mechanics and a more brazen attitude can only compensate so much for physical deficiencies. Even following some of the tips offered here won't mean these three starters suddenly turn into rocket-armed passers.
But it shows that adjustments can be made to help weaker-armed quarterbacks still add big-play potential to their offenses.
