i think it goes like this

at the height of linsanity, rockets owner alex mandated (not nicely) morey to get lin. in return morey goes, ok, it's your money. you want it, you got it. thus the poison pill contract is born. but the fact remains that mchale and morey was never high on lin and could never get over that predisposition. it was obvious from the short leash lin had last season, and unltimately made blatant this season by benching lin to an inferior player over the 'fit' hyperbole. basically the rockets owner alex loaded a gun and morey turned it and shot him in the foot.
