CLEVELAND, Ohio -- You can see it, David Blatt is struggling.
Ever since Kyrie Irving and Iman Shumpert returned to health, the Cavaliers coach can't quite figure out how to use his entire roster. His rotations have been more like a knuckleball than a sharp slider. They sort of float and drift with a mind of their own.
Any knuckleball pitcher will tell you that he aims for the heart of the plate, tries to take as much spin off the ball as possible -- and then let the wind and elements take over.
With the Cavs, LeBron James is the heart of the team.
