Spotrac has the numbers even more favorable for the team
http://www.spotrac.com/nfl/green-bay-packers/cap/ Almost 30million with roll over from 2015.
I can't say I've seen enough from Pennel to consider Raji expendable. Raji has a pretty good season at the Nose, but he would need to come back knowing he is probably just a run down and short yardage player and will be subbed out on passing situations. I'd be OK with him getting a couple million a year for that role.
Nick Perry is another guy where it would depend on how much money it takes to keep him.
But even 30 million doesn't go far in the NFL these days.
The world needs ditch diggers too Danny!!!
