I think the move would be a wise one, but I suspect the organization of this "committee" was more a PR move only. It basically served to surround the owner with a shroud of legitimacy that dispelled any perception that he was an advocate of the messages delivered to Jonathan Martin in this mess.
If Ross can surround himself with people who have credibility with regard to 1) the Dolphins (i.e., Shula, Marino, and Moore), 2) the NFL (i.e., Dungy and Shula), and 3) the African-American race (i.e., Moore, Dungy, and Martin), then he will have gone a long way toward making this look like a "Richie Incognito" problem and nothing more, elevating the perception of him "above" the mess.
