@richkae - Hate the game, not the player. From the coverage I saw, the metric is medals. By that criteria, it's simply a mathematical exercise.
I don't hate the player. Phelps is the greatest swimmer ever. He is also the most decorated olympian ever. You can even call him the "greatest Olympic champion ever" because it probably means exactly the same as "most decorated olympian ever".
I just hate the Costas. Just because that talking head says something over and over and over doesn't make it true. Phelps is not "the greatest athlete ever".
