Every offseason, NFL teams hope they can upgrade their team through free agency. Some teams choose to spend a ton of money to land a big fish while others go after bargain-basement players.
One thing is for sure, there are a number of free agents that could instantly improve any team. Here are five key free agents on the offensive side of the ball and where they could possibly land.
Doug Martin, running back
After two subpar seasons, Martin bounced back in a big way for Tampa Bay in 2015. The running back finished second in the league in rushing last season with 1,402 yards.
The Buccaneers failed to work out a deal with Martin before he hit free agency. If he doesn't re-sign with the team that drafted him 31st overall in2012, the New York Jets or Dallas Cowboys could make their respective pitches to Martin. Both the Jets and Cowboys will be looking to upgrade their backfields Martin appears to be a great fit for both teams.
Matt Forte, running back
In 2015, Forte recorded a career-low in rushing yards (898) in his eighth season with Chicago. At age 30, there's one team that would be a perfect fit for the running back and that's the New England Patriots.
The Patriots have had a history of having older running backs on their roster (Corey Dillion, Fred Taylor, Steven Jackson) and Forte's skill set would fit in perfectly with the offense.
Dion Lewis is a decent young running back, but he is coming off a torn ACL injury and after finishing 30th in the league in rushing last season, it’s pretty clear backfield depth is something the Patriots need to address this offseason.
Lamar Miller, running back
Miami had hoped to come to an agreement with Miller before free agency, but the two sides have been unable to come to terms.
Reportedly, Miller and his agent Drew Rosenhaus are seeking a contract that pays the 24-year-old more than $5 million per season. While the Dolphins might not be able to pay that much for Miller, teams like the New York Giants or Tampa Bay (if they don't re-sign Doug Martin) could be options for Miller.
Russell Okung, tackle
There are a number of teams looking for help on the offensive line, specifically at tackle. Instead of a team using a draft pick on a bookend up front, it could choose to go the free agent route instead. Okung figures to be one of the more appealing tackles on the market this offseason.
While Okung has said he would love to stay in Seattle that doesn't seem very likely to happen. With Donald Penn possibly not re-signing with Oakland, the Raiders could be a landing spot for Okung, especially given how much cap space the team has to work with. Tennessee and San Diego also could inquire about Okung's services.
Travis Benjamin, wide receiver
Last season was a breakout campaign for Benjamin, who recorded 68 receptions for 966 yards and five touchdowns for Cleveland. More impressively, Benjamin racked up those numbers catching passes from the Browns’ revolving door at quarterback – Josh McCown, Jonny Manziel and Austin Davis.
Cleveland and new head coach Hue Jackson will likely try and re-sign Benjamin, but the free agent could have plenty of suitors. Tampa Bay, San Diego and the Los Angeles Rams are just a few of the teams that could be looking to upgrade their wide receiver depth this offseason.
