I agree with coaching change... but Riley holds some of the blame. Wade and Lebron don't fit well together, and while he's tried to surround them with low utilization, high % shooters - they have all been injured.
I really think the team would best be served trading Wade... something like Dwight, JJ, Turk for Wade, Bosh, and Miller. Doesn't that make sense for both teams?
Miami: Dwight, Haslem, Lebron, JJ, Chalmers + some spare part big men, Turk, Battier, and Cole. Seems like a much better put together team. They could run the old Orlando ball handler + 3 shooters + Dwight lineup too, except they'd have Lebron as ball handler instead of Turk or Nelson.
Orlando: They have two priority 1 problems right now: Dwight Howard wants out and is dragging the team down, and Turk has a terrible contract. Solve both, while getting a superstar wing and all star big man. I don't love that team as much as Miami, but they are much further away.
Too logical though, so probably won't happen.
