With their carryover from last year’s salary cap, the Green Bay Packers have about $7 million in cap space for the 2013 season.

But that number will increase over the next few weeks and perhaps more than triple, depending on general manager Ted Thompson’s roster moves before the start of free agency in March.

The biggest decisions for Thompson and coach Mike McCarthy are whether to keep a couple of highly paid but older veterans in defensive back Charles Woodson and inside linebacker A.J. Hawk.

Woodson is a likely future Pro Football Hall of Famer but also at an advanced age (36) that makes him a target for release. If the Packers cut him, they would pick up $10 million in cap space. They also could try to work out a pay cut, with Woodson able to make back some or all of the difference with playing-time incentives, but there’s a chance the Packers won’t want him back at any price if they think that they have to get younger and more athletic in the secondary.

If the Packers cut Hawk, they could save $5.45 million in cap room. Hawk, who has been a starter since his rookie season of 2006, is 29, an age when many NFL players have begun to decline, depending on position.

The Packers likewise could try to work out a pay cut with Hawk, but they also will have to consider whether they need to get faster and more athletic at linebacker regardless of salary.

Among the inside linebackers on their roster, the Packers will return two from serious injury: Desmond Bishop, who is coming back from a torn hamstring, and D.J. Smith, who sustained a torn anterior cruciate ligament Oct. 14 at Houston. Another, Brad Jones, is an unrestricted free agent who might be retained at a palatable price. And they have two young and unproven inside linebackers in Terrell Manning and Jamari Lattimore.

Thompson liked Manning enough to trade up for him in the fifth round of last year’s draft; Lattimore, 24, moved from outside linebacker to inside linebacker only last year.

If the Packers cut Woodson and Hawk, they’d pick up $15.45 million in cap room.
