He did say he just wasn't able to play his game. I guess that's reason enough for most people (of course it could be more than that, but how are we ever to know). Of course he is (past his use by date). As for being unable to win anything... well that's not really a certainty. Not worth arguing over though. But he's still better than most players. So there's no reason to quit. If he enjoys the game, go for it :S. And yes, provocative is the word.
