MIAMI — For the second time in two days the Miami Heat have lost a guard from their NBA Finals starting lineup. After losing point guard Gabe Vincent on Friday to the Los Angeles Lakers at the start of NBA free agency, the Heat on Saturday lost shooting guard Max Strus to the Cleveland Cavaliers in a sign-and-trade transaction. Unlike with the loss of Vincent, the Heat received compensation, albeit nominal, in the Strus transaction, which grew into a three-team trade also involving the San Antonio Spurs.
