I think that when you're the best in the world at something and you have been for awhile, then you have to find a way to challenge yourself that may be something different than what most can use. I think that last year his win probably was about conquering personal issues since he was in the middle of a divorce, etc. and this year may have been about doing something no one else has ever done .... that 6th win ... and he has to work in a way so he hasn't peaked yet for the year since it is an Olympic year and I'm assuming he's planning to participate there .... though I haven't followed things closely this year so I'm not certain of that.
