Seeing as there's only 3 more rounds, it's time to start looking at UDFAs as the Bills will likely have to bring in around 17-20 players (UDFAs/Veteran UFAs) depending if they make any more moves today with picks.
Here are a few of my favorite players from smaller schools and a few from larger schools that may be undrafted.
WR/TE- Ricky Seals-Jones, Tex. A&M (6'5", 243lbs, 4.6): Redzone threat, can be split out wide or play as off the line TE.
Slot WR- Keevan Lucas, Tulsa (5'9", 192lbs, 4.5): 238 rec, 3200yds, 32 TDs in in 41 games.
RB- Justin Davis, USC (6'0, 208, 4.5): One cut & go, downhill runner.
C/G- Johnny Caspers, Stanford (6'4", 300, 5.4): Interior player with good feet, ZBS prospect.
CB- Jamal Agnew, San Diego (5'9", 185, 4.3): 48 PBU & 11 INTs, size concerns.
S- David Jones, Richmond (6'1", 205, 4.4): Playmaker but has history of injuries, 14 INTs
SS/LB- Josh Harvey-Clemons, Louisville (6'5", 228, 4.7): Tweener/sub package type of prospect.
OLB- Keenan Gilchrist, App. St (6'0", 230, 4.5): WLB prospect, totaled 25 TFL & 7.5 sacks
OLB- Ukeme Eligwe, Georgia Southern (6'1", 235, 4.5): Older prospect but HWS guy.
