It's matches like these that make you think Djokovic would have been a great character in the 80s along with Borg, Connors, and Mac.
Connors and Mac were enough for those times, especially in the non hawkeye era where they'd go wild because of bad calls...and then harbour a grudge for the rest of the match which was equally as funny...one drama begetting another one. Those were the days.
Today, most players have become lobotomized because the human error has been removed. Djoker has to work extra hard to find things to be dramatic about!
Perhaps he uses these medical timeouts on purpose to rope-a-dope the crowd. IDK.
