Jets free-agent market watch: David Harris

With free agency set to begin March 10, we'll examine the New York Jets' top free agents over the next few days:

Player: David Harris

Position: Inside linebacker

Age: 31

Previous contract: He made $36 million over a four-year contract.

2014 stats: Recorded a team-high 124 tackles, including 73 solo. Also had six sacks, five tackles-for-loss and two forced fumbles. He played 99.4 percent of the defensive snaps.

The case to keep him: There's no heir apparent on the roster and the free-agent market is thin. If they part ways with Harris, a mainstay since 2007, they'd be looking at the likes of Brandon Spikes and A.J. Hawk (released Wednesday by the Green Bay Packers). Harris isn't a flashy, Pro Bowl-type player, but he's smart, consistent, durable and selfless. The man has no ego whatsoever; he's team-oriented all the way. Obviously, he'd have to learn a new defensive system under Todd Bowles, but it wouldn't be a major transition. With a ton of cap room, the Jets would look silly if they let one of their heart-and-soul players walk away.

The case to let him go: There's only one negative -- his age. Harris has played eight years at a physically demanding position, so you have to worry about wear and tear taking a toll at some point. Then again, Bowles isn't opposed to having an older linebacker in the middle of his defense. He got a solid year out of Larry Foote, 34, last season with the Arizona Cardinals. Like Harris, Foote attended Michigan. They make 'em tough in Ann Arbor.

Crystal ball: There is motivation on both sides to hammer out a deal, so look for something to get done before March 10. Our prediction: A four-year, $24 million contract, including $12 million in guarantees. Karlos Dansby, 33, signed the same deal last year with the Cleveland Browns. D'Qwell Jackson, 31, signed last year with the Indianapolis Colts for four years, $22 million, including $11 million guaranteed. Harris will have no shortage of suitors. The Miami Dolphins, Buffalo Bills, Atlanta Falcons and Chicago Bears reportedly have interest.
