2013 NFL Draft quarterback ratings

Although Barkley may not be a flawless prospect like Andrew Luck or an athletic marvel like Robert Griffin III, he would have been a top-five pick in the 2012 NFL Draft. Barkley has an excellent feel for the game and an arm that is strong enough to make most throws. Will need to get better on deep ball accuracy. Because of where he goes to school and his laid back nature, analysts will be trying to figure out whether or not Barkley the next Matt Leinart.

In his first season replacing Ryan Mallett, Wilson was eased into college football with arguably the best receiving corps in the nation. With it, Wilson threw for 3,638 yards and 24 touchdowns while completing 66.9 percent of his passes with just six interceptions. As a senior he'll have less talent around him, which will prove if he's a top prospect. It's somewhat concerning that Wilson struggled last season in Arkansas' biggest games against Alabama and LSU. He's close to Barkley as a prospect, however.

Smith has solid size and athleticism, but he's so highly rated because he's confident in the pocket and has a good arm. As a senior, Smith has to get the ball out quick and needs to improve his deep-ball accuracy. How much will the play of Brandon Weeden affect Smith's draft stock? There are concerns about how players transition from the Dana Holgerson offense to the NFL.

From the standpoint of reading defenses and being a pocket passer, Manuel has a way to go. So how is he rated so highly? When Manuel can roll out of the pocket, he's impressive. Manuel has a strong arm and can make throws all over the field. He also has a nice touch and gets good placement on his passes.

When everything is in its proper place for Jones, he can be a very good quarterback. But when his offensive linemen and wide receivers got hurt, he struggled. Jones' size and ability are solid, but he's often tentative in the pocket and doesn't read the defense well.

Glennon has finally bulked up and taken over the quarterback reigns for NC State. Glennon has good timing on his drops and can really spin the football. He just needs to become more consistent game-to-game. In his first year as a full-time starter, though, Glennon threw the second-most touchdowns in a season for the Wolfpack.

It can be somewhat difficult to evaluate Renfree due to where he plays. Has good size. Because of the pieces around him at Duke, an all-star game will be key for Renfree.

In his first year as a starter, Vandenberg expectedly went through some growing pains. Still, he threw for more than 3,000 yards and 25 touchdowns. He's a solid pocket passer with above-average physical tools.

The 2011 season was a forgettable one for Tuel. He broke his clavicle and only played in three games, throwing for just 276 yards on the season. Even when healthy he didn't get on the field late in the season. But Tuel has a good arm and should get to show it in Mike Leach's offense.

Carder is a tough quarterback with more experience than most players on this list. He's already thrown for more than 7,000 yards on his career to go with 61 touchdowns. He has a good enough arm to zip passes with accuracy outside the hashes. He's athletic too, but not overly dependent o his ability to run.

At times in 2011, like against Miami when he completed 92 percent of his throws passing for 310 yards and three scores, Thomas looked liked a surefire No. 1 overall pick whenever he enters the draft. But at others, like his two-interception performance against Clemson, he desperately looked like a player in need of more experience. As he develops this year, we'll find out whether or not Thomas will live up to the potential he showed against Miami. He certainly has the size and natural ability to become the top pick and live up to the Cam Newton/Ben Roethlisberger comparisons he receives.

During his sophomore season, Bray was up and down largely due to a broken thumb suffered in October. His height is an obvious plus, though he's rail-thin for a quarterback. He gets rid of the ball with a proper over-the-top release, but would do well speeding it up. He has a good understanding for the offense, though, and a lot of talent around him.

The separation between Bray and Price is minimal and Price has the skills to be a superstar. He'll always get compared to RG3, so just embrace their similarities. Price can deliver on a variety of throws and showed good accuracy and ball placement on passes near the sideline. Played through knee injuries as a sophomore.

Murray sparkled at times last season — particularly against Auburn, South Carolina Georgia Tech — but has been inconsistent. Against LSU and Florida, Murray completed less than 45 percent of his passes in 2011. He's known as a hard worker in the film room and has the natural physical skills for the NFL. Most will look at Murray's size and question his upside. But his release point is good and he's probably as tough as any player in the nation.

Although Pachall has a ways to go in reading defenses, some expect him to become a better quarterback for TCU than Andy Dalton. He certainly has better size and a much stronger arm.
