‘Tagliabue appointed Houston, Green Bay, Cleveland, Detroit and St. Louis to the committee in a memo issued around the NFL on Monday, league spokesman Greg Aiello said Tuesday. Aiello said two more teams, representing the league’s lower-revenue franchises, will be added soon to complete the eight-member committee. Buffalo was the first team appointed last week after Bills owner Ralph Wilson complained the new collective bargaining agreement reached last month, which added a new revenue sharing model, threatens the financial viability of his and other small-market teams.’
