The NFL is fast approaching its free agency period, with teams set to begin talking with unrestricted free agents on March 7, and players are free to sign with any team at 4 p.m. ET on March 9. Moving forward, let’s take a look at the top unrestricted free agents who are most likely to hit the market.

Eric Berry, S, Kansas City Chiefs

The Chiefs starting safety returned from his cancer scare playing an elite level, something that many teams in the league will be looking for in their secondary. Berry finished his 2015-16 campaign with 61 tackles, two interceptions and 10 pass deflections.

Doug Martin, RB, Tampa Bay Buccaneers

The 5th-year running back will be coming off of his best year as a starter in terms of yards per-carry. Martin averaged 4.9 YPC, gaining 1,402 yards and reaching the end zone six times.

For a team in dire need of a feature back, Martin showed his worth in 2015 in Tampa Bay, finishing second in the league in rushing.

Matt Forte, RB, Chicago Bears

While not the back he used to be, Forte showed no signs of slowing down due to age in the 2015-16 season. Forte, despite missing three games in weeks 9-11 and being limited in the second half of the season, finished with 898 yards, four touchdowns and averaged 4.1 YPC.

Although not the backfield threat he once was, Forte could offer a value upgrade at a key position to a lot of teams looking for rushing help.

Russell Okung, OL, Seattle Seahawks

Okung, though not great, has been a solid starter at tackle for the Seattle Seahawks since being drafted in 2010. And in a league where protecting your quarterback has become the key component to winning, and a market low on talented line help, Okung would be a great pickup for anyone looking to upgrade their offensive protection.
