Assuming you're not being sarcastic....
Are you (and all other Kovtun haters) going to dwell on 2013 for
how long? He was a junior essentially sent to Senior Worlds -- he was slated to do badly from the get-go and the Russian fed put a goldfish in a shark tank. Are you honestly criticizing him for not having a destructive career just because he couldn't get 2 Olympic spots which no other Russian man (other than Plu) would have gotten anyways?
Also, Kovtun is liked by the judges (a little too much... and Voronov isn't for some reason), but his federation doesn't give him a ton of special treatment -- he didn't even get to go to the Olympics -- when was the last time the reigning Russian champion didn't go to the subsequent Olympics? Hah, "special treatment" indeed.
Kovtun might be a brat, but he's been the only Russian to beat Plushenko since Yagudin, is a 2-time National champion, has medalled at all four GP events in his first two senior seasons including 2 wins (and not outrageous wins... he wasn't great, but he was still the best of the field in each and skated an excellent FS at TEB to win gold), was 4th at just his second Worlds (in what most would *legitimately* call his first "senior" season), and also came 2nd at Euros this year. Technically speaking -- he added a second 4T to his LP during his junior season, had a comparatively consistent 4S by the following season (and a 3-quad LP), and is one of the only men in the field to have attempted (and landed) 2 quads in his SP.
As for Gachinski, he has no notable results since his well-earned 2011 World bronze other than a 2012 Euro silver. He's never placed higher than 5th in ten Grand Prix appearances (compared to Kovtun who has 2 silvers and 2 golds in his four Grand Prix appearances). Gachinski's career destruction was his own doing. Kovtun bombed at 2013 Worlds and came back the next season on fire winning 2 GP silvers and Russian Nationals (but was jipped of going to the Olympics by Plu who was given the spot essentially on reputation - sorry, a "closed test skate" and without having to compete at Euros -- talk about special treatment!

). And this year, he won 2 GP golds and Russian Nationals again, and a Euros silver. Worlds was dicey, but he had no shot at a medal anyways given how Fernandez/Hanyu/Ten performed.
