A fine example indeed.
Another good one is when Matt Serra defeated Georges St. Pierre, they put him as the #1 Welterweight. No argument there. Why, then, after Chieck Kongo defeats Mirko Cro Cop, or after Forrest Griffin defeats Shogun, are they not ranked above the men they defeated?
If you're making the argument that a win over someone means the winner should be ranked higher than the loser, an argument which I wholly support, then you must be consistent with it. If you are arguing that an entire resume means more than even a head to head matchup between two opponents for rankings, then, again, at least be consistent to that ideal. This mixing and matching completely devalues the rankings.
Though, in your example, Kang's loss to Misaki was under somewhat dubious circumstances. I believe Kang had a broken arm and (and I could be remembering this incorrectly) I think the sentiment was that Misaki had been awarded a "home town decision." But then, are ranking "authorities" meant to be judges as well and dictate if a decision was correct, or should they rank based on actual outcomes, even if the circumstances weren't perfect for both fighters?
I think about these things. I get the feeling that MMAWeekly does not.
