Someone else alluded to this...
Rodgers - 19.5 mil (12.4% of cap)
CM3 - 13.7 mil (8.9% of cap)
Shields - 12 mil (7.7% of cap)
Peppers - 10.5 mil (6.8% of cap)
Cobb - 9.1 mil (5.9% of cap)
Jordy - 8.3 mil (5.3 % of cap)
To be fair, next on the list are Daniels, Lang, Burnett, Bulaga, and Perry who have all been relatively to significantly impactful this year. With that said, aside from Rodgers (maybe) there isn't a Pro Bowl caliber player in the top six, and obviously three have missed significant time to injury or have might as well have (Peppers).
