The Buffalo Bills agreed to terms with 14 undrafted free agents after the conclusion of the draft Saturday. Here's a closer look at each player:

Glenn Gronkowski, FB, Kansas State: The youngest of five Gronkowski brothers who hail from nearby Williamsville, New York, "Goose" will try to carve out a role with the Bills as a fullback and H-back. At 6-foot-2 and 239 pounds, he's a more compact version of his older brother, Rob, a tight end for the New England Patriots.

Eric Striker, ILB, Oklahoma: A second-team All-America selection by the Associated Press, Striker likely went undrafted because of his lack of size -- he's 6-feet and 221 pounds. However, he proved a productive college player, starting 13 games each of the last three seasons. He finished his career at Oklahoma with 191 tackles, 46.5 tackles for a loss and 23 sacks. With the Bills' inside linebacker depth chart thinned out this offseason, he could stand the best chance of any Bills undrafted rookie of cracking the 53-man roster.

Bryson Albright, OLB, Miami (Ohio): At 6-foot-5 and 225 pounds, he might need to bulk up to play outside linebacker in Rex Ryan's 3-4 defense. He started 35 games in college as a defensive end, tallying 180 tackles and 19 sacks. The Bills' depth chart is crowded at his position, so Albright's best bet to stick will be to develop on the practice squad.

Davonte' Allen, WR, Marshall: He brings some size to receiver, standing 6-foot-2 and weighing 201 pounds. Allen had 58 catches, 715 yards and five touchdowns last season, so if he can translate his college production into a strong training camp, he might stand a shot to earn a spot in a wide-open receiver competition behind Sammy Watkins and Robert Woods.

Gary Chambers, WR, Arizona State: At 6-foot-4 and 215 pounds, he will match 2015 seventh-round pick Dezmin Lewis as the tallest receiver on the Bills' roster. Chambers had 36 catches for 690 yards and four touchdowns last season.

Reid Ferguson, LS, LSU: The Bills have one of the best long-snappers in Garrison Sanborn, but Ferguson will get a look this summer.

Rob Kugler, C, Purdue: He's plenty familiar with the Bills, having played at nearby Orchard Park High School while his father, Sean, served as the Bills' offensive line coach from 2008-2009. Kugler started 43 consecutive games for Purdue and was a two-time captain. He'll compete with Fernando Velasco and others for the backup center job behind Eric Wood.

Jamison Lalk, C/G, Iowa State: He served as a center last season after beginning his college career at guard. He was a second-team All-Big 12 selection last season and will compete with Kugler and others for a backup interior offensive line role.

Claudell Louis, DE, Fresno State: The Bills need some depth at defensive end in Ryan's 3-4 defense, and Louis has ideal size at 6-foot-5 and 294 pounds. His college production doesn't stand out -- he was only an honorable mention All-Mountain West selection last season -- but he'll get a look from the Bills.

Marquis Lucas, T, West Virginia: He started 30 games at both left and right tackle, and with Seantrel Henderson's health status uncertain, the Bills could use some depth at that spot in training camp.

Keith Lumpkin, T, Rutgers: He was an honorable mention All-Big Ten selection last season, his third consecutive year as Rutgers' starting left tackle. He's also massive, standing at 6-foot-8 and 325 pounds.

Marshall Morgan, K, Georgia: His 407 points are third all-time in Georgia history. The Bills' kicker job could be up for grabs this summer after the Bills restructured Dan Carpenter's contract this spring to incentivize more of the deal.

Julian Whigham, CB, Syracuse: He'll make the trip down Interstate-90 after playing in 43 games for Syracuse. He's a long shot to make the 53-man roster at one of the Bills' deepest positions.

Justin Zimmer, DE, Ferris State: Like Louis, Zimmer has the ideal size (6-foot-3 and 292 pounds) to play defensive end in Ryan's 3-4 defense. He's a distinguished Division II prospect, having earned first-team All-Great Lakes Intercollegiate Athletic Conference honors for three consecutive seasons.
