Nothing about the Cleveland Cavaliers offense screams sustainable in a playoff setting. With postseason success being the ultimate goal in Cleveland, even with all of their struggles, they need to evolve.
With an offensive rating of 115.8, hovering around the top-10, the results could certainly be much worse than they have been. Beyond those numbers, the issue is with how quickly this will all fizzle for the Cavaliers when it matters most.
Cleveland has not just built their offense on the 3-point shot, but they have relied on it to a point of fault. They are chucking 44.
