Here's a list from another site of some UFA's, not your high priced guys, but rather the under the radar type guys that could come cheap and be able to improve this football team
Deon Grant, S, Jacksonville Jaguars (Age 28)
Grant might be the best "under the radar" player in this class. After spending his rookie year on IR, he hasn't missed a game in six seasons. Over those six seasons (for the Panthers and Jags), he's averaged three INTs and over 60 tackles a year. He's a ballhawk type, and if you're looking for a guy who can handle receivers over the top, he's it.
Mike Gandy, T/G, Buffalo Bills (Age 28)
No, Gandy isn't a franchise left tackle, but neither is Leonard Davis. Gandy is much cheaper, though, and he's just as versatile. He's played all over the line in his career. Last year, he played left tackle for the Bills and played it well, helping JP Losman to a breakout year. He held Jason Taylor and John Abraham sackless. He's much better in pass protection than Sims is, and he can play guard.
Antwan Peek, DE, Houston Texans (Age 27)
Peek is one of those undersized college D-ends who was converted to a 3-4 outside linebacker. Well, that took him away from what he does best - rushing the passer with his hand on the ground - and wasted the first three years of his career. He returned to rush end last year and showed some flashes. He's 6'3 250 and could be a very good, cheap source of 3rd down pass rush off the edge in our system along with Burgess.
Alex Stepanovich, C, Arizona Cardinals (Age 25) (RFA)
Stepanovich, former Ohio State star, lost out to Nick Leckey in the center battle and has been doing spot duty since in Zona. He's young, he's big (6'4 312) and he's athletic. At this point in Jake Groves career, It's not looking like we have solved the problem at center....Stepanovich would be an upgrade. He could still be a very good starter for somebody. I doubt the Cards will give him a high tender, considering he's the backup. He could be a real steal.
Rien Long, DT, Tennessee Titans (Age 25)
I read he's unrestricted, though he seems young. Anyway, I like this kid. He's a natural pass rusher, with nifty moves and good burst. Had he been healthy last year, he'd be too expensive for this list. He spent the year on IR, though, so he could be a bargain. In the two full seasons he's played, he had 8.5 sacks just from the DT position.
Tony Fisher, RB, St. Louis Rams (Age 27)
At one time, Fisher was considered an up and comer with the Packers. He was buried in St. Louis last year, but he's still a solid runner. He's well built (6'1 222) and has good career rushing numbers in spot duty. He also has great hands in the passing game. He'd be a nice backup package for the Raiders.
