Who are the impact players remaining in NFL free agency?

Once DeMarco Murray was scooped up by the Philadelphia Eagles, that unofficially ended the first phase of free agency.

The big ticket items are all taken now, but that doesn't mean teams with remaining salary-cap room are out of luck. There are plenty of players who can come in and help right away.

Let's look at the best of the rest, among those who were still available as of Friday morning:

DE Greg Hardy: We all know the deal. If it weren't for the domestic violence issue last year, he'd have been one of the prizes of free agency. But as is, he still waits for a job. The Raiders were rumored to be interested in Hardy, but it might be a tough sell to Raiders owner Mark Davis, who has been outspoken about the domestic-violence issue in the NFL. I honestly figured Hardy would get more attention than he has, because teams conveniently realign their moral values when talented players are involved, but Hardy's market has been either slow or teams are keeping their interest very quiet.

WR Michael Crabtree: Apparently people are down on Crabtree. He rushed back from an Achilles injury in 2013, and although he played well for the San Francisco 49ers at the end of that season, he slipped in 2014. Maybe that was because of the quarterback play, but there hasn't been much buzz about him.

RB Reggie Bush: Bush talked to the San Francisco 49ers but didn't sign there right away, but whether it's in San Francisco or elsewhere he should find work soon. He could still be a very valuable role player, especially as a receiver out of the backfield.

TE Charles Clay: Clay isn't unrestricted, because the Dolphins put the transition tag on him. So they can match any offer. But after Miami signed Jordan Cameron, it seems likely that Clay is moving on elsewhere. The Bills seem quite interested.

C Stefen Wisniewski: The Oakland Raiders decided to let Wisniewski go and pay big bucks for center Rodney Hudson to come over from the Kansas City Chiefs. Wisniewski was reportedly visiting the Seahawks, and a deal there after Seattle traded Max Unger in the Jimmy Graham deal makes sense.

DE Michael Johnson: Just because he had a bad season in 2014 doesn't mean he's finished. The admittedly mismanaged Buccaneers dropped a massive contract on Johnson, one of the headliners of last year's free agent class, just a year ago. He has a shot to rebound in 2015.

LB Rolando McClain: One of the NFL's most surprising stories last year, former first-round pick McClain reemerged to have a nice year with the Dallas Cowboys. With Justin Durant off to the Atlanta Falcons and Bruce Carter off to the Buccaneers, the Cowboys really need to re-sign McClain.
