Clay Mathews should remain a hybrid player, imo. Either add another stud inside line backer or at least another outside linebacker (hopefully both) which would free up Clay even more. Hopefully they can find an inside linebacker that can cover.
I don't expect any free agent splashes this year, unless they lose guys like Peppers, Tramon, fail to resign Raji, Guion, etc. As long as the Packers have another good draft, they should be a contender again next season. My biggest fear, as always, is health. If the Green Bay Packers stay as healthy as they did this season, they are competing for a Super Bowl almost every season.
