Dethroned last week as NBA champions, the Cleveland Cavaliers are stepping into a summer already off to a strange start. With the draft just days away, and major roster decisions — maybe even a blockbuster trade for Paul George — needing to be made, the Cavaliers aren't certain who will be calling the shots going forward as they attempt to close the gap on the Golden State Warriors. General manager David Griffin's contract expires June 30, and it remains unclear if he will stay with the organization he guided to its first championship and three straight NBA Finals.
