From the bargain bin: The best undrafted players of 2013

Every year, right after the draft is over, NFL teams get on the phone with hundreds of kids who didn't hear their names called during the actual selection process. For any number of reasons, there are times when teams miss out on potential, or develop it later, and benefit from the ultimate bargain score -- the undrafted player who turns into a starter -- and, on occasion, a Pro Bowl or Hall of Fame-level asset. From Kurt Warner to John Randle to Rod Smith to Antonio Gates to Wes Welker to London Fletcher and on and on, there's always enough of a chance that a few of these payers will hit on the bigger gamble to make them worth monitoring.

Here, based on what we've seen, are the best players still left standing once the 2013 NFL draft was done, and the teams they've signed with in parentheses.

Da'Rick Rogers, WR, Tennessee Tech: A Greg Cosell favorite. NFLDraftScout.com gave him a third-round grade. Was suspended indefinitely from the Tennessee squad for violations of team rules and subsequently transferred, but dominated at the bigger-school level, as well. Big kid (6-foot-3, 217) with 4.5 speed and interesting after-catch abilities. If he gets his act together, could be a legitimate starter. (Buffalo Bills)

Matt Scott, QB, Arizona: Mobile quarterback with some pretty serious mechanical fixes ahead of him, but he really intrigues as an athlete and thrower. Not just a guy who runs around in the pocket -- has the speed to threaten upfield. Could be a long-term NFL backup and spot starter in the Seneca Wallace mold, and perhaps more than that with a team willing to take the shot on developing him over time. (Jacksonville Jaguars)

Alvin Bailey, OG, Arkansas: Big but agile blocker with the ability to protect in space and at the second level, but can also bring it with power at the line. Can play right or left guard. Struggles with more advanced defensive concepts and is erratic in play-to-play blocking consistency. Needs an NFL team that understands how to bridge the gap between potential and performance. (Seattle Seahawks)

Tyler Bray, QB, Tennessee: Impressive arm talent with question marks just about everywhere else. Annoyingly erratic thrower who benefited from a great deal of receiver talent. Not an effectively mobile player when he needs to be and doesn't really have a gauge with his arm strength. Has some reported off-field concerns, and there could be more underneath the surface. Buyer beware, but someone will fall in love with the cannon and try to deal with all the other stuff. (Kansas City Chiefs)

Kwame Geathers, DT, Georgia: Father, uncle, and brother played, or currently play, in the NFL. Massive run-stuffer with surprisingly quick feet and a certain level of burst off the snap. Dropped because he's got a lot of technique work to do -- he loses power a lot on leverage, doesn't show a lot of effective hand movement, and disappears for long stretches of time. Rotational guy at the NFL level. (San Diego Chargers)

Chase Thomas, OLB, Stanford: Lacks speed to the ball and doesn't display a lot of agility in space, but could catch on with a team able to use and appreciate his football smarts. Understands stunts and blitzes at a high level. Effort guy who will max out on technique. Stronger than his size (6-foot-3, 244) would indicate. (New Orleans Saints)

Kevin Reddick, ILB,North Carolina: Straight-line guy with the speed to blitz. Led the ACC with 18.5 tackles for loss in 2012. Has played through injuries. Needs to be in a defense where he's in a lane and isn't asked to move around too much, but teams in need of a thumper could do a lot worse. (New Orleans Saints)

Xavier Nixon, OT, Florida: Looks the part, but has struggled with a lot of technique stuff. Injuries kept him from a combine workout, which affected him more than most because NFL teams would want to know why his play dropped off after a strong freshman campaign. Tape shows that he struggles in space and fails to deliver consistent leverage blows. Like most athletically gifted big men on his list, he's here because he needs to do the finishing work. (Washington Redskins)

Tony Jefferson, S, Oklahoma: A 5-foot-11, 213-pound box player with some coverage ability and short-area speed concerns that may make him a niche downhill player and could limit him in slot situations. Could excel on special teams if he can learn to tackle with more force and better technique. (Arizona Cardinals)

Conner Vernon, WR, Duke: Highly productive player in an offense the NFL respects -- the ACC's all-time leader in receptions and receiving yards. While Vernon understands routes in short areas, he lacks athleticism that would have teams looking harder at him. He'll need the right fit, but will probably gain his quarterback's trust over time and could surprise in the next few years. (Oakland Raiders)

Cierre Wood, RB, Notre Dame: Off-field concerns may have dropped his stock -- suspended the first two games of the 2012 season. Kind of a tweener, with some speed to get upfield, but he should block a lot better at his size and needs to develop more consistent power. (Houston Texans)

Lerentee McCray, OLB, Florida: Fast player with some quarterback pressure potential, but needs to get the motor under control. Has some coverage ability, shows a natural attack demeanor, and could be a good situational defender at the next level. (Denver Broncos)
