one has to be careful with the evidence of wear and tear or an impending physical condition. our own sean elliot failed a physical that would have sent him to the rockets from detroit (thank goodness). the evidence of kidney disease was there but it was not an immediate threat. doctors could not state that the condition would worsen, just that it was a possibility, and though it did take 5 years, sean's kidneys did fail. with raheem there is evidence to suggest that an arthritic condition could arise. how soon? no one can say-but GM's are not much into gambling when it comes to big dollars and contracts.
