Per NFL.com:
The Player Advisory Council will meet regularly throughout the year with Commissioner Goodell and NFLPA Executive Director Gene Upshaw to discuss competition on the field, player safety, medical and health issues, player conduct, retired player issues, and other matters.
I also think it's interesting that Goodell, in conjunction with the NFLPA, has formed this committee to discuss retired players issues, since it was a branch of the NFLPA that recently requested that a court dismiss a suit against them brought by 3,500 actual retired players for inadequate representation -- no conflict of interest there. Who actually represents the actual 3,500 actual retired players with actual legal concerns over the actual handling of actual retired players issues is anyone's guess, actually.
That's not entirely fair, as just because the NFLPA participated in naming the council doesn't mean the individuals involved are in the Player's Association's pocket, though it does raise some concerns. That said, the new council is made up (from what I can tell) of outstanding veterans including one of Your Washington Redskins:
