Shock Boom Boom tactic blew up in Novak Djokovic's face Would Novak Djokovic have serve-volleyed at match point without Boris Becker in his courtside box? Are they incompatible because Djokovic's preferred role of Minister of Defence is the abject opposite to Becker's commando-rolling, risk-taking mantra? Is Djokovic unnecessarily complicating his career by trying to sprinkle his fortified game with Becker's renowned panache? Rather than being an inspiration, is Becker a distraction? Are they doomed? Djokovic won four Australian Opens because he was the ultimate warrior. He cultivated long and gruelling rallies. The resilience was extraordinary. He parked himself on the baseline and absorbed punches until finally, when a Rafael Nadal (2012) or Stanislas Wawrinka (2013) were out on their feet, he would pull the trigger. There were no short cuts. No cheap points. In the biggest moments of the most humungous matches, Djokovic would serve-volley as often as he went out to dinner with Nadal. Never. Ever.
