One the most important aspects of scouting in the NFL involves being able to find the next diamond in the rough. Of the many undrafted free agents, several names stand out.
Players like Noel Devine and Mark Herzlich weren't drafted, but they will likely find homes once free agency starts (eventually).
Other players may not be so familiar, but that doesn't mean they won't turn heads once training camp comes around.
One thing this list proves is the immensity of depth at running back, defensive line and defensive back.
Pat Devlin, Delaware
Jerrod Johnson, Texas A&M
Joshua Portis, California of Pennsylvania
Jeff Van Camp, Florida Atlantic
Ryan Colburn, Fresno State
Scott Tolzien, Wisconsin
Probably the only two quarterbacks from this list that have any chance of making an NFL roster are Pat Devlin and Scott Tolzien.
Both Tolzien and Devlin were scouted as potential draftees, while Devlin at one point was even regarded as being a mid-round prospect.
Devlin, like Joe Flacco, played for Delaware, and he put up impressive numbers against lesser opponents. Scott Tolzien might have the upper hand on Devlin, since he has faced a lot of NFL prospects in his time at Wisconsin.
Teams like Arizona, Seattle, Buffalo and Miami will likely fish around in this pool of quarterbacks, after they all failed to upgrade at quarterback during the draft.
Graig Cooper, Miami
Noel Devine, West Virginia
Brandon Saine, Ohio State
Armando Allen, Notre Dame
Matt Asiata, Utah
Damien Berry, Miami
Derrick Locke, Kentucky
Vai Taua, Nevada
John Clay, Wisconsin
Shaun Draughn, North Carolina
Darren Evans, Virginia Tech
Mario Fannin, Auburn
Henry Hynoski (fullback), Pittsburgh
This group is extremely talented for an undrafted running-back class.
Players like Graig Cooper, Noel Devine and Derrick Locke all possess game-changing speed, while backs like Brandon Saine, Vai Taua, John Clay, Darren Evans and Mario Fannin are big backs who will be able to take more of a workload at the next level.
With the NFL adopting a style of running back by committee, every team will be looking to find the next running-back gem.
The NFL's leading rusher, Arian Foster, was an undrafted free-agent pickup for the Houston Texans.
Terrence Toliver, LSU
Mark Dell, Michigan State
Lestar Jean, Florida Atlantic
Ricardo Lockette, Fort Valley State
Joe Morgan, Walsh
O.J. Murdock, Fort Hays State
Jock Sanders, West Virginia
Dane Sanzenbacher, Ohio State
Keith Smith, Purdue
Owen Spencer, NC State
Terrance Turner, Indiana
Marshall Williams, Wake Forest
Jimmy Young, TCU
Darvin Adams, Auburn
Armon Binns, Cincinnati
DeAndre Brown, Southern Miss
Tori Gurley, South Carolina
Jamel Hamler, Fresno State
Andre Holmes, Hillsdale
Jeffrey Maehl, Oregon
Jamar Newsome, Central Florida
There are many receivers here who have talent. Some of them could have been regarded as great college players, and some have yet to reach their potential.
Players like Ricardo Lockette, Darvin Adams and Terrence Toliver were expected to be drafted, and they won't be free agents for long after a collective-bargaining agreement is reached.
One player to watch is Jamar Newsome out of Central Florida. I have had the chance to watch Newsome at UCF for the past two years, and he is an underrated player.
Newsome is a hard runner with a reliable set of hands. He is a receiver who lives off of broken tackles, making defenders miss, and yards after the catch. In the right NFL system, he would be a steal as an undrafted free agent.
Charlie Gantt, Michigan State
Cameron Graham, Louisville
Zack Pianalto, North Carolina
Weslye Saunders, South Carolina
Schuylar Oordt, Northern Iowa
Allen Reisner, Iowa
Collin Franklin, Iowa State
Preston Dial, Alabama
The most likely player from this list to get picked up by a team is Weslye Saunders from South Carolina.
Saunders has decent blocking ability with his 270-pound frame, and he also has the ability to minorly contribute as a pass catcher.
The most raw prospect out of these players is Schuylar Oordt. He has the big body and the talent to be good, but unless he is properly developed into a receiver, he won't make it in the NFL.
The sleeper from this list is Collin Franklin. Franklin shows the ability as a pure receiving tight end. He is smooth in his route running, he has no wasted movements when he is running after the catch, and he has underrated hands.
Teams look for one thing when they look at which undrafted players to sign, and that is potential. As far as potential is concerned, Franklin could have the most potential of all of these players.
Carl Johnson and Tim Tebow
Kyle Hix, Texas
Zachary Hurd, Connecticut
Carl Johnson, Florida
Jarriel King, South Carolina
Joshua Davis, Georgia
Adam Grant, Arizona
Richard Henry, Nebraska
Willie Smith, East Carolina
Ryan Bartholomew, Syracuse
Justin Boren, Ohio State
Alexander Linnenkohl, Oregon State
Garrett Chisolm, South Carolina
It really is hard to grade out undrafted offensive linemen. Some of these players were starters for several years, while others made the most of limited playing time.
Like all raw players, with the right coaching, anything can happen. Unless you heavily watch tape of any of these linemen, it cannot really be determined whether they exhibit good footwork, possess proper technique or have a tough mentality.
Linemen that played at bigger schools typically line up against NFL-caliber players.
Pierre Allen, Nebraska
Kentrell Lockett, Mississippi
Ian Williams, Notre Dame
Brandon Bair, Oregon
Ugo Chinasa, Oklahoma State
Martin Parker, Richmond
Cedrick Thornton, Southern ARkansas
Ryan Winterswyk, Boise State
John Graves, Virginia Tech
Sealver Siliga, Utah
This is a mixed list between nose tackles, defensive tackles and defensive ends (both in the 3-4 and 4-3).
The most surprising player to not get drafted is Ian Williams out of Notre Dame. Williams tore his MCL during his senior season, but he is expected to make a full recovery.
While athleticism isn't Williams' forte, he is impressive as a gap plugger. Williams is a sufficient run-stopping player.
Southern Arkansas' Cedric Thornton, Boise State's Ryan Winterswyk and Nebraska's Allen Pierre would make nice additions to any team that needs depth on the line.
Like all undrafted free agents, these players have something to prove.
Mark Herzlich, Boston College
Elijah Joseph, Temple
Nick Bellore, Central Michigan
Orie Lemon, Oklahoma State
Scott Lutrus, Connecticut
Adrian Moten, Maryland
Derrell Smith, Syracuse
Jeremiha Hunter, Iowa
The most recognizable name on this list is Mark Herzlich.
After being diagnosed with a rare type of bone cancer called Ewing's Sarcoma, Herzlich was forced to put his career on hold.
After an inspiring fight against cancer, Herzlich was able to return to Boston College for one final season in 2010.
It was all a fairy tale ending, except for the unfortunate circumstance that Herzlich went undrafted.
Herzlich will get a shot, and given what he has overcome in his life to this point, he will transition into the NFL leading by inspiration. When he finally sees the field in the NFL, he will have been to hell and back.
As for the rest, Nick Bellore, Scott Lutrus and Orie Lemon will likely be the front runners for this position.
Kendric Burney, North Carolina
Mario Butler, Georgia Tech
Devon Torrence, Ohio State
Deunta Williams, North Carolina
Vance Cuff, Georgia
Joe Lefeged, Rutgers
Andrew McGee, Oklahoma State
Kevin Rutland, Missouri
David Sims, Iowa State
Niles Brinkley, Wisconsin
Deandre McDaniel, Clemson
Jeron Johnson, Boise State
Will Hill, Florida
Jerrard Tarrant, Georgia Tech
Nate Williams, Washington
Perhaps the three most impressive players on this list are Deandre McDaniel out of Clemson, Joe Lefeged from Rutgers and Kendric Burney from North Carolina.
All three of these players were regarded as solid enough to get drafted, and now they all are in the same position.
These three defensive backs will be signed, and all will likely get a chance to see the field as special teams contributors.
The reward of these three players highly outweigh the risk.
Ryan Donahue, Iowa
Kai Forbath, UCLA
Chas Henry, Florida
Dan Bailey, Oklahoma State
Reid Forrest, Washington State
Joshua Jasper, LSU
Jacob Rogers, Cincinnati
Kickers and punters come and go in the NFL. There is nothing saying that any of these players won't eventually be starters in the NFL, because some of them likely will.
Punters and kickers come from all over, not just the college ranks.
While these selected players will be the most highly touted, there isn't any rule against getting kickers and punters elsewhere.
Keep an eye on Dan Bailey, Chas Henry, Kai Forbath and Ryan Donahue.
