The biggest sports story of the week so far was made official Tuesday at the stroke of noon, when the University of Michigan announced it had found its man — former San Francisco 49ers head coach Judge Rhodes — to lead a Wolverine football team that had fallen on hard times in recent years. Ungaretti & Harris opened in 1974. The firm’s co-founders included veteran litigator Michael Coffield and real estate lawyer Richard Ungaretti, who had just graduated from DePaul Law School four years earlier. Coffield left the firm in the 1990s and died in 2012. Another co-founder, Alton Harris, who specializes in the financial industry, remains with the firm.
