So either he doesn't actually know the rules, or he does but he's pretending not to so he can blame them when he does badly? Any national or Olympic level athlete should know the rules of their sport inside out and backwards, particularly when they present a road map for winning. And if they don't like those rules, then they either need to do something productive to change them (by offering tangible alternatives, getting on the review committees, submitting proposals etc), or stop competing within that sport. To use either ignorance or act like you are above the rules is just making excuses, rather than taking responsibility for your own performance. I think the reason he's come back to competition is because he's run out of other options.
