NFL Draft 2013: Late-Round Picks Who Will Be Surprise Stars

The 2013 NFL draft is in the books, and several teams improved with the additions to their roster. But some NFL teams improved because of the players they essentially stole with their late-round picks.

They did not expect these players to fall to them in the rounds they did, but they are more than happy with their unexpected luck.

Here we break down the late-round picks that will be surprise stars for their respective teams in 2013.

Matt Barkley: Philadelphia Eagles

The Philadelphia Eagles selected Matt Barkley with the first pick of the fourth round, with the No. 98 overall choice.

Many believed Barkley would be drafted much higher, but to the Eagles' fortune, he fell to them on the third day.

In his four-year career as a starter at USC, he threw for 12,327 yards and 116 touchdowns.

He brings a wild card into the quarterback mix in Philadelphia, which already has Michael Vick, Nick Foles and Dennis Dixon. However, he's the first QB selected under new head coach Chip Kelly, so he already has a slight advantage over the rest of the candidates.

Barkley could sneak into the starting role if Vick falls with an injury, which is likely to happen. If he can get his feet wet and learn Kelly's system, Barkley could become a star QB in the NFL.

Barrett Jones: St. Louis Rams

The St. Louis Rams selected Barrett Jones with the 16th pick of the fourth round, with the No. 113 overall pick.

One of the most decorated college football players in the game's history fell to the third day of the draft. But he will be an immediate starter on the Rams' new-look offensive line.

The Rams added tackle Jake Long via free agency, and with Jones, St. Louis bolstered its front line in front of quarterback Sam Bradford.

Jones' ability to play center and guard at the next level will allow him to fill whatever need the Rams have on the inside of its offensive line. Don't be surprised if he makes an appearance in the Pro Bowl in his rookie season.

Quinton Patton: San Francisco 49ers

The San Francisco 49ers selected Quinton Patton with the 34th pick of the fourth round, with the No. 131 overall pick.

The Louisiana Tech wide receiver caught 183 passes for 2,594 yards and 24 touchdowns in his collegiate career.

He was not projected to be an early-round wideout, but San Francisco obtained him at a bargain rate late in the fourth round.

Patton will step in and provide Colin Kaepernick with another weapon on offense. He will add depth to the receiving corps alongside Michael Crabtree and Anquan Boldin.

He should have a very productive first year at the professional level.

Jesse Williams: Seattle Seahawks

The Seattle Seahawks selected Jesse Williams with the fourth pick in the fifth round, with the No. 137 overall pick.

Williams was predicted to be a late first-round, early second-round pick, but he plummeted down the board and fell into the Seahawks' hands.

His run-stopping skill set will allow the edge rushers in Seattle to cause more mayhem in opponents' backfields. He makes an already suffocating defense even more lethal.

Williams may not be a Pro Bowler, but his presence on the defensive line will force offenses to run outside toward his lingering teammates.

Stepfan Taylor: Arizona Cardinals

The Arizona Cardinals selected Stepfan Taylor with the seventh pick in the fifth round, with the No. 140 overall pick.

During his career at Stanford, Taylor rushed for 4,300 yards and 40 touchdowns.

He has proven to be a consistent running back with the skill set that translates well to the next level.

The Cardinals didn't have a potent running game, but after the draft, they might have found their every-down back. He could be the surprise offensive rookie in this year's draft class.
