I dislike arbitrary reasoning behind any of those decisions. It should be decided based on something real. Or at least something fairly level.
Makes you think, when drafting... it doesn't hurt, if you draft well, to fill any leftover slot with a starting QB that you'll probably never play.
If you tie, you can't really take too much pride in the win, no matter what the tiebreaker. Your roommate is kind of a dork.
