A number of the top NFL free agents have re-signed or found new homes at this point, but there are still some difference-makers out there, ranging from the offensive line to the defensive line to the backfield.
Whether it's an aging star or a running back coming off multiple foot surgeries, there are still some high-level players out there who simply haven't found the right fit (or the right price) yet.
Here's a look at the top players currently on the market (2012 teams in parentheses).
Andre Smith, OT (Cincinnati Bengals)
Despite Bengals head coach Marvin Lewis saying the "sun is emerging" in negotiations to re-sign Andre Smith (via Joe Reedy of the Cincinnati Enquirer), Geoff Hobson of Bengals.com wrote on Thursday that "nothing looked imminent."
Many believe the Bengals will draft an offensive tackle in the first round in case they can't re-sign Smith.
It's no wonder why Smith believes he's worth a lot. To put it bluntly, he is. He was ranked by Pro Football Focus on March 29 as one of the top remaining offensive tackles in free agency. Among this year's crop of free-agent offensive tackles, he received the second-highest grade in 2012 by PFF.
Brandon Moore, G (New York Jets)
Brandon Moore may be 33 years old, but he should frankly have a job by now. He proved in 2012 that he still can be a difference-maker.
Among this year's class of free-agent guards, Moore was ranked the best by PFF in 2012, outperforming former Buffalo Bills guard Andy Levitre (now with the Tennessee Titans).
What may be slowing the demand for Moore (beyond his age) is the fact that he is asking for starter's money, according to Ian Rapoport of NFL Network, via Rotoworld.com. Such a price tag can range from $3.5 million to $7.8 million. Still, on a short-term contract, Moore provides an instant boost to most teams' lines.
John Abraham, DE (Atlanta Falcons)
John Abraham's price tag is way too high now for his age (34), but if he lowers his demands a bit he figures to get snatched up quickly. Several teams—including the New Orleans Saints and the Miami Dolphins—have expressed interest in him. There's also a chance the veteran re-signs with the Falcons.
Abraham is simply too old at his position to be asking for the kind of money he is, but he's a nice short-term option if he lowers his asking price.
Among free-agent edge defenders this year, Abraham was ranked No. 2 in 2012 by PFF. He was ranked No. 1 among free-agent defensive ends.
His production speaks for itself. He has 122 career sacks (13th all-time), and he's posted at least 9.5 sacks in each of the past three seasons (10 in 2012).
Ahmad Bradshaw, RB (New York Giants)
Ahmad Bradshaw has had three surgeries on his right foot since 2009. You could say this was the result of freak injuries, but at this point it's difficult not to call him injury-prone.
But the fact remains: When Bradshaw is on the field, he's one of the most complete backs in the NFL. He can run, catch passes out of the backfield and block with the best of them.
While this year's crop of running backs wasn't spectacular, Bradshaw did rank first in the group in 2012. In 14 games last season, Bradshaw rushed for over 1,000 yards and six touchdowns on 4.6 yards per carry and caught 31 passes for 245 yards.
