Why should Kevin Durant’s broken foot occasion any surprise? The five-time NBA scoring champ has been a three-time league leader in minutes played. And he’s averaged another 42 minutes a game over 73 playoff games since 2010 – the equivalent of another full season. And his summers? Busy, busy, busy. There was the 2010 world championship in Turkey, some nine games between August 28th and September 12th, capping ten weeks’ worth of preparation and exhibitions. In 2012, it was on to an Olympic gold medal: Eight games between July 29th and August 12th – altogether, two months of preparation, exhibitions and eight actual games in London. Foot problems still a surprise?
