CLEVELAND — Kyle Korver could soon be hoisting shots for the NBA champions. The Cleveland Cavaliers are trying to finalize a deal to acquire Korver, one of the league’s elite 3-point shooters, in a trade from the Atlanta Hawks, a person familiar with the negotiations told The Associated Press on Thursday night. The sides are closing in on a deal, but the particulars “‘are not clear,” said the person who spoke on condition of anonymity because the deal has not been completed.
