The NFL Draft is over, but general manager still have a chance to find a diamond in the rough with undrafted free agents.

After drafting seven players, the Eagles signed a whopping 15 free agent rookies on Saturday night. The 22 new players over the past few days brings the Eagles roster to 87 players.

So who are these undrafted rookies that will try to catch on with the Eagles? Here is a look at the 15 players added after the draft.

Trey Burton, WR/TE, Florida:

Height: 6-foot-2

Weight: 224 pounds

Projected Round: 7th round/UDFA

Scouting Report: Very good athlete. Natural hands-catcher. Catches in stride and adjusts very well to the flight of the ball. Keeps working to uncover and has a good feel for zones. Good route runner. Sets up defensive backs and can create some separation out of his breaks....Has short arms and is very undersized for a tight end. Lacks run strength and does not power through tackles or create much yardage after contact. Marginal blocking strength and overall length to sustain and can be overwhelmed. Lacks top-end speed to mismatch safeties. (via NFL.com)

Fit with Eagles: The Eagles love pass-catchers that can play receiver and tight end, and Burton has experience at both.

David Fluellen, RB, Toledo:

Height: 5-foot-11

Weight: 224 pounds

Projected Round: 7th round/UDFA

Scouting Report: Excellent size. Runs hard downhill and can pick and slide and find creases. Good vision, leg churn and contact balance to finish runs. Tough and physical -- squares his shoulders to the line and will seek to deliver punishment. Nice balance and agility. Can power through arm tackles. ......Average speed. Tends to run a bit upright. Can do a better job of securing the ball tightly -- will flag it. Limited make-you-miss. Lacks home-run speed to pull away from the pack. Is not a nuanced pass protector -- developing eyes and awareness. (via NFL.com)

Fit with Eagles: The Eagles are thin at running back after trading Bryce Brown. Fluellen will have a chance to make the team.

Carey Spear, K, Vanderbilt

Height: 5-foot-9

Weight: 194 pounds

Projected Round: 7th/UDFA

Scouting Report: In his first full season of starting action, Spear emerged as one of the SEC's elite kickers, nailing 20 of 24 field goal attempts, all 27 PATs and averaging 60.6 yards per kickoff (including 22 touchbacks). He's hardly just another unathletic kicker, as well, notching three physical tackles on kick return duties in 2012. Spear was named to the Preseason All-SEC team in 2013. If he can build upon his impressive junior campaign amid this spotlight, he could rise into draft-worthy consideration. (via CBS Sports)

Fit with Eagles: The Eagles do not seem in love with their current kicker, Alex Henery. They are likely hoping Spear gives Henery a run for his money.

The Eagles' new kicker can also do this, which should make him a fan favorite in the competition with Henery:

Josh Andrews, OG/C, Oregon State

Height: 6-foot-2

Weight: 300 pounds

Projected Round: 7th/UDFA

Scouting Report: Positive: Three-year starter at left guard with experience at the center position. Quick, versatile blocker with limited upside. Fires off the snap, stays square, and keeps his feet and hands active throughout the action. Explosive at the point, shows ability pulling across the line of scrimmage, and blocks with good lean.

Negative: Stiff, struggles to adjust and ineffective blocking in motion. Overextends into blocks and does too much clutching of defenders. (via DraftInsider.com)

Fit with Eagles: The Eagles are thin at guard, with only Evan Mathis and Todd Herremans on the roster.

Kadron Boone, WR, LSU

Height: 6-foot-0

Weight: 193 pounds

Projected Round: UDFA

Scouting Report: Emerged as LSU's No. 3 receiver as a junior in 2012 and is expected to hold that role again in 2013 ... Played in 40 games with 11 starts ... Has 37 receptions for 482 yards and six TDs to his credit ... The six TD receptions are the most of any player on the active LSU roster ... Has combination of good speed, size and route running ability ... Received the Alvin Roy Fourth Quarter Award in the spring of 2012 for outstanding performance in the off-season program. (via CBS Sports)

Fit with Eagles: The Eagles are stacked at receiver, and with Boone standing under 6-foot-3, he is going to have to really impress on special teams.

Henry Josey, RB, Missouri

Height: 5-foot-8

Weight: 194 pounds

Projected Round: UDFA

Scouting Report: Short, darting, change-of-pace zone runner who will have to carve a niche as a third-down back. With a son to support and the memory of a gruesomely severe knee injury in 2011 (torn ACL, MCL, meniscus and patellar tendon), left school early despite tepid draft projections. Is the type you root for, but will have to prove his chops as a receiver and pass protector to stick. (via NFL.com)

Fit with Eagles: The competition at backup running back for the Eagles is wide open, and Josey has a chance with his 4.43 speed in the 40-yard dash.

John Fulton, CB, Alabama

Height: 6-foot-0

Weight: 194 pounds

Projected Round: UDFA

Scouting Report: Fulton was a January enrollee for the Tide in 2010 and gained valuable experience during spring drills ... has developed a role in nickel and dime formations ... has been a key special teams performer during his first three seasons at the Capstone ... played in 36-career games with 23 tackles and eight pass breakups ... has two-career starts and will push for an expanded role as a senior in 2013. (via CBS Sports)

Fit with Eagles: The Eagles are deep at cornerback, as they added Jaylen Watkins in the fourth round on Saturday. Fulton will have to knock off either Roc Carmichal or Curtis Marsh, and even that might not be enough.

Quron Pratt, WR, Rutgers

Height: 5-foot-11

Weight: 191 pounds

Projected Round: 7th/UDFA

Scouting Report: Named Rutgers MVP last season after posting 32 receptions for 516 yards. Quick, dependable receiver who plays bigger and faster than his size and speed numbers. Runs sharp routes, quickly gets into breaks then stays low on exit. Separates from opponents, uses his frame to shield away defenders, or gets vertical to come down with the difficult reception. Displays good eye-hand coordination, takes a big hit but holds onto the throw. Effective kick returner. Minimally productive until his senior season. Comes with poor measurables. (via DraftInsider.net)

Fit with Eagles: The Eagles worked out Pratt, and while it was believed they had more interest in Pratt's teammate -- receiver Brandon Coleman -- it looks like they came away more impressed with Pratt.

Daytawion Lowe, S, Oklahoma State

Height: 5-foot-11

Weight: 194 pounds

Projected Round: UDFA

Scouting Report: Cannot be relied upon to play man coverage with tight ends consistently at this point because he is too grabby when he's at a disadvantage. He draws holding calls too often. He will have to learn to look back for the ball and play for the ball to avoid the penalties. (via Bleacher Report)

Fit with the Eagles After adding two safeties on Saturday, it's hard to imagine any UDFA making their way onto the Eagles -- especially a safety like Lowe, who is flagged often.

Frank Mays, DE, Florida A&M

Height: 6-foot-9

Weight: 291 pounds

Projected Round: UDFA

Scouting Report: A two-year letterman at Florida A&M, Mays played in 11 games for the Rattlers as a senior in 2013 and led the team in sacks (4.0) while ranking second with 10.5 tackles for a loss. The Bemidji, MN, native appeared in 21 total games in his college career, tallying 68 tackles, 15.5 tackles for loss and six sacks. (via Philadelphia Eagles)

Fit with Eagles: Mays comes from a tiny school, but there is nothing tiny about this defensive end. Mays is long and athletic, which means the team will give him every chance to show what he can do.

Blake Annen, TE, Cincinnati

Height: 6-foot-4

Weight: 247 pounds

Projected Round: 6th

Scouting Report: Moderately productive tight end who moved into the starting lineup as a senior. Efficient, blocks with solid fundamentals, and shows terrific vision. Fluid releasing of the line into pass routes, displays good movement skills, and solid eye-hand coordination. Takes a big hit but holds onto the throw. Terrific athletic.

Negative: More of a one-speed tight end and does not play to his forty time. Average strength at the point of attack. (via Draft Insider)

Fit with Eagles: Cincinnati Bearcats have a history of working out for the Eagles, as center Jason Kelce, linebacker Connor Barwin, and tight end Brent Celek all went to Cincinnati. Annan is athletic enough to keep the trend going, as he ran a 4.44 in the 40-yard dash.

Donald Hawkins, G, Texas

Height: 6-foot-4

Weight: 301 pounds

Projected Round: 7th/UDFA

Scouting Report: Hawkins arrived in Austin in the spring of 2012 and quickly earned the starting LT job, starting 11 games protecting the quarterback's blind side last season. He played two seasons at Northwest Community College where he didn't allow a sack in his 19 starts at the JUCO level. While he doesn't have elite height and length for the tackle position, Hawkins showed enough in his first season at the FBS level to catch the eyes of scouts around the NFL. (via CBS Sports)

Fit with Eagles The Eagles went heavy on offensive lineman among their UDFA, which shows they know they need some of them to pan-out and make the team.

Karim Barton, G, Morgan State

Height: 6-foot-2

Weight: 314 pounds

Projected Round: 7th/UDFA

Scouting Report: Junior-college transfer who started the past three seasons at right tackle. Bends his knees, sets with a wide base, and strong at the point of attack. Stays square, anchors in pass protection, and easily gets positioning on defenders. Jolts opponents with terrific hand punch and makes good use of blocking angles. Keeps his head on a swivel, displays good awareness, and blocks with a nasty attitude. Not light on his feet and struggles if asked to pull across the line of scrimmage then block in motion. Lacks lateral range and footwork in pass protection. (via DraftInsider)

Fit with Eagles: The Eagles are desperate for backup offensive guards, a good thing for Barton.

Wade Keliikipi, DT, Oregon

Height: 6-foot-2

Weight: 303 pounds

Projected Round: 7th

Scouting Report: Three-year starter who finished the year with 34 tackles, 5 tackles for loss, and 2 sacks, all career bests. Hard-working college lineman with limited next level potential. Quick off the snap, plays with good lean and fights with his hands. More of a one-speed tight end and does not play to his forty time. Average strength at the point of attack. (via DraftInsider)

Fit with Eagles: The Eagles are looking for a big body to backup starting nose tackle Bennie Logan, as they Damion Square had an up-and-down season last year. Keliikipi will be given a chance, especially since he is a former Oregon Duck.

Kevin Graf, T, USC

Height: 6-foot-6

Weight: 309 pounds

Projected Round: 6th/7th

Scouting Report: Graf earned honorable mention All-Pac-12 honors following his senior season of 2013. He was a three-year starter at USC, where his father lettered three years as an offensive guard and played on their 1972 National Championship squad. His brother, Derek, lettered at center for USC in 2002. (via Philadelphia Eagles)

Fit with Eagles With his size and weight, Graf could play his way onto the practice squad.
