Ranking does not matter!

Then why have rankings? How can rankings not matter? If rankings do not matter, why play professionally? If rankings do not matter, don't tell me we excel for the sake of excellence. Actually, excellence, probably, does not matter. Only ranking does. Thanks to rankings, there is an attempt to work towards excellence. Without rankings, there would be no incentive to excel. Therefore Mr. Dhoni, rankings do matter. They better matter. Because when something doesn't matter, it's that much easier to not see it going to your head.
