I think this is accurate. I don't know a lot of professional football players, but I'll bet that the majority of them have a huge amount of respect for gold jacket wearers and yearn to be included in that club someday. It may not mean much to us as fans, but I'll bet it means everything to the players and coaches.
Regarding the LOB, the only slam dunk that I see is Bobby Wagner. Earl probably makes it if they don't hold some of his off-field issues against him. Kam was never named 1st team All Pro and appeared in the Pro Bowl just 4 times. Beast has an uphill battle, never led the league in rushing, a lot of his peers ahead of him on the all-time rushing list, ie Adrian Peterson, Shady McCoy, Stephen Jackson, et al.
Both Pete and Russell were borderline a few years ago and needed something extra on their resumes, a league or SB MVP for Russell and another Lombardi for Pete, but both have recently blown whatever chance they may have had.
