Maybe the week of rest will do him good. He seemed really tired in Rio, except for today, a bit.
don't really know why.
he blew away at least two of his opponents.
he really needs to start getting more fit again. clay season gets more and more grueling as he gets older.
he has 2-3 years left at the top max. he has to try to take a shot at history.
perhaps the bad back is keeping him from doing some track work.
Maybe the back issue didn't allow him to prepare the way he would have in the past. He seemed to be just trying it out in Rio, and then went all the way to the final, so maybe that's why he was exhausted.
