The NFLPA has released their rankings of all the NFL teams and their remaining cap room for 2013.
Surprise, surprise—the Green Bay Packers have more money left over than any other NFC North team, as well as the majority of NFL teams overall.
The NFLPA report puts them at just under $18 million.
The Packers have always been frugal in free agency, much to the consternation of their fans, though this year I have felt as though they've been saving for a reason.
Clay Matthews is also due a new contract, though some reports, such as one by Chris Wesseling at NFL.com, say he might have to wait until Rodgers has his.
Regardless, you are—at the very least— looking at two big contracts for two of the key foundation pieces of the team.
There are also likely to be other contracts—B.J. Raji come to mind—which require a significant amount of money.
As you can roll over cap room from this year to the next, it makes sense that the Packers save themselves some money now so they can spend on their players later.
