Is the King of the Mountains an also-ran?
The King of the Mountains is the best climber in the Tour, right? This year I have had zero interest in who is in the polka dot jersey because the best climber is in yellow, its Nibali. He has won 4 stages but isn't winning this competition. It is pretty clear what the criteria for the yellow and white jerseys are. The Green jersey is said to be a sprinters jersey, though in reality it is for the most consistent finisher. Peter Sagan has evinced the spirit of this jersey by finish in the top 5 in the first week on sprints, climbs and pavé.
Meanwhile the KOM jersey passes hands between some breakaway riders, until we get to the high mountains where all the real points are. Then it comes down to who is low enough down on the GC to be not a threat. Yellow will attack if a mountain breakaway is considered a GC threat, so lower order riders are allowed to just scoop up points until the last climb which turns into a GC bunfight. The KOM jersey passes hands up the field until it gets to about 3/4/5/6th then stalls. I don't see how yellow dictating who can breakaway and who is reigned in makes it a prize to be cherished. As far as I am concerned the KOM is nearly always the yellow jersey (apart from 2012 when you-know-who took most of his time on the TTs.)
