The Jacksonville Jaguars are a team that's in need of a rebuild, but they're also a team that at are in position for a roster overhaul. The Jaguars will have quite a few players hit the free agent market in 2013.

Here's a quick rundown of the players on the defensive side of the ball that will be free agents:

• LB Daryl Smith
• CB Derek Cox
• CB William Middleton
• DE John Chick
• DE George Selvie
• DT Terrance Knighton
• LB Kyle Bosworth
• CB Rashean Mathis

Like the offensive side of the ball, I don't really see any "must keep" players for a rebuilding effort outside of Derek Cox, which becomes tricky. Cox is a young ascending player, but he struggles to stay on the field and has missed 17 of his last 40 games. The question becomes how much do you pay him? Do you franchise tag him, with about a $10 million hit? It's possible you could bring back Daryl Smith on a short-term deal while you're trying to rebuild, but again cost comes into play and whether or not Smith wants to try to latch on to a team closer to winning it all.
