Derek Carr Scouting Report:
Arm strength and accuracy
Carr has the best arm talent of any quarterback in this 2014 NFL Draft. That may seem like a strong statement, but he proved it time and time again throughout the last two seasons. Even when his mechanics fail him, Carr can put the ball in any spot on the field with velocity, timing and accuracy. Additionally, Carr has exceptional touch and accuracy on his deep passes.
Comparing Carr to Matthew Stafford or Jay Cutler is not a stretch in this department. Regardless of his arm slot, footwork or the spot on the field he's throwing to, Carr can put the appropriate velocity on the ball. He's also an accurate passer in most areas of the field. Think about the throws that are important for an NFL quarterback to make: vertical routes, throws to the sidelines and throws into tight windows.
There are times when Carr's accuracy fails him, but we'll touch on that later.
Fresno State's offense called for vertical passes and screens. There wasn't a ton of in-between. Carr also spent most of the time lined up in the shotgun formation. Reading defenses while dropping back is a bit of a different process. That learning curve shouldn't be steep for Carr, though, based on the habits he's shown in college.
Unfortunately, it's tough to get enough of a feel for how Carr reads defenses because of his offense. He was asked to make relatively simple reads that won't necessarily translate to the NFL.
And here's where we start getting into some of the negatives to Carr's game. His mechanics, particularly in his lower body, are inconsistent at best. He often throws off of his back foot and doesn't transfer his weight properly when throwing the ball. He also lets his throwing mechanics be affected by pressure in the pocket, whether it's rushing his throw and not paying attention to his arm slot or not taking the time to focus on proper lower body mechanics.
Sounds like someone in the 2017 draft..
