It is in great measure on Harden getting fat and happy in the summer..but they aren't trading him..he is 4-years younger and more durable than a soon to be breaking-down Howard who would be demanding an albatross contract..
I think the obvious next move for team that has chronic issue with effort/discipline, which stems from the bad exmple their best player sets, is to hire a no-nonsense coach who has enough pedigree to crack the whip..The only available option on the market that fits that is Tom Thibodeau but that will likely come with the emasculation or firing of Morey....If Harden doesn't get straightened by Thibs , then you simply ship his ass and move on...
