When the draft ends, all eligible players who weren't picked in the draft become fair game and teams scramble to snap up guys they may have interest in. The Eagles especially have done a great job with their undrafted free agent signings in the past with guys like Quintin Mikell, Joselio Hanson, & Jamal Jackson.
So far, these are the guys that have agreed to terms with the Eagles.
RB Marcus Thigpen, Indiana - Scouting report - Small, very fast running back. Good return man.
DE Josh Gaines, Penn State - Bio - Big run stopping defensive end.
WR Brandon Robinson, Boston College - Bio - Went from the Eagles to the Eagles!
S Reshard Langford, Vanderbilt - Langford is a strong safety. His coach had this to say Reshard will make a huge impression on the Philadelphia coaches with his talent, effort and desire to help anyway he can,” VU coach Bobby Johnson said. “He was tremendous here, both on and off the field. Reshard Langford is one of those guys you build winning teams around."
OL Dallas Reynolds, Brigham Young - Profile
RB Walter Mendenhall, Illinois State - A "big" back. 6'0 225. Brother of Steelers RB Rashard Mendenhall, who was a 1st round pick last year.
FB Marcus Mailei, Weber State - 248 pound fullback that can catch.
K/P Sam Swank, Wake Forest - Scouting report - Primarily a kicker that has punted... Has 50+ range.
