first problem with your logic: you are assuming we won't get the GSW pick. i still think we will.
second problem with your logic: you're assuming that a 14th pick in the draft (marcus morris, patrick patterson, earl clark, anthony randolph, al thornton, ronnie brewer, rashad mccants, kris humphries, etc.) is going to be such a difference-maker that it's worth more than the invaluable playoff experience we'd be giving favors, hayward, burks, etc.
the 14th pick is not a huge asset. look at that list. not a single impact player on that list. thornton was good for a minute but now is out of the league. patterson is in and out of houston's lineup. brewer is a role player. it took humphries 7-8 years to become the 4th best player on a lottery team.
and you want that over the playoffs -- THAT's mind-boggling.
