If the draft is really 4 deep (and the difference between 5 & 6 is relatively small), that would be reason to win, not to lose.Going from a 10% chance at 6th to a 20% chance at sixth in a draft that imho is 4 deep is reason enough to lose.
The odds of a top-4 draft choice don't change no matter what happens tomorrow. EDIT: other than what @gandalfe said a few posts above. (So the better way to say it is we can't increase our odds of top 4 by losing tomorrow.)
