You must be joking?
Four years he is doing preparation for Sochi 2014, and you expect him to drop before single event? There is no logic in what you are saying. I imaging he will drop only of his health. But other than that nothing will stop him from competing in single event.
Less than two years ago he did Euro 2012, and he skated three clean programs within five days. He has most experience than anybody else to skate more the two programs in one competition. Did you know that?!
His main competitor is himself, and if he skates clean this balanced program no one will beat him. Plushenko just showed everyone he is using same game as everybody else this time.
Of course Russian needs to have decent substitute, that is why all Russian athletes training very hard right now, including Kovtun.
