It isn't a sad way of looking at the sport, you're just not looking at reality. I wish cycling were ridden the way it was back in the 80's (and before), with the big champions lining up to win the classics, the Giro and the Tour and the Worlds in one season, but it simply is no longer the case. I'd even settle for the Giro-Tour double being a real obective for the most talented engines, but even this has succumbed to the crushing weight of going for the most coveted prize in the sport, the maillot jaune. The lion's share of all sponsorship visibility throughout the whole season, takes place over three weeks around France. The best of the best, in each discipline, show up in their absolute best form to contest individual stages, but only the most talented overall rider takes highest honors in Paris.
Now, in today's sport, if you are capable of winning the Tour (Giro and Vuelta), the classiscs (at least several) and the Worlds (unless a pan flat course) - and Pog has this potential - then hands down you are the best in the peloton. Whereas if you are capable of winning everything else, except the Tour (or perhaps any grand tour), you don't deserve that honor imo. Even if your only win the entire season was the Tour, by right you enter the top two or three on this acheivement alone. That's how huge the French stage race is. It is at least refreshing that today's crop of potential tour winners is looking to win elsewhere too, for example in certain classics, which hasn't really been the case since the 80s. I hope it continues, but I fear the business/sponsorship interests will kill even this if in any way this threatens success in France in July.
