Those blue UNIGLO shorts Djokovic was wearing for the US Open final looked really tight on him. The leg openings looked really small and skinny. Could these "skinny" shorts have restricted his movement so that he couldn't stretch, flex, and move as well as he normally could? Is this an extension of the skinny jeans trend? Djokovic relies on his incredible movement and flexibility to amazingly get to almost every ball. Could his tight shorts have restricted his major weapon?
