It's not common sense at all because then you'd wind up with 14 teams after the winner of the 13/16 and 14/15 game was decided. From there you'd have to have 3/14, 4/13, 5/12, 6/11, 7/10/, 8/9 before finally making it to the quarterfinals. Now you've got the tournament going 5 days, and making it pretty much impossible for any of those 4 bottom seeds to win anyways, so what's the point?
