Some consider it progress but most agree there’s a long way to go. “There’s still work to be done in this area, no question about it,” Pittsburgh Steelers team president Art Rooney II said Thursday. The Houston Texans hired David Culley this week, making the 65-year-old longtime assistant the league’s third Black head coach hired. The New York Jets previously hired Robert Saleh, the son of Lebanese immigrants and the first NFL head coach who is known to be Muslim. Culley and Saleh join Pittsburgh’s Mike Tomlin, Miami’s Brian Flores and Washington’s Ron Rivera as the league’s only minority head coaches. In a sport where about 70% of the players are minorities, the lack of diversity among the head coaching ranks sticks out.
