For all his remarkable consistency and being one of the four pillars that carried the game for decade, there were two periods of a year each that immortalized the Muzziah of professional tennis.
July 2012 to July 2013 - After reaching his first Wimbledon final, he wins his first Olympic single gold, wins the USO, reached the final of AO, won Miami, won Queens and won Wimbledon.
December 2015 to November 2016 - Wins Davis Cup, reaches the final of AO, wins Rome, reaches final of RG, wins Queens, wins his second Wimbledon title, wins his second single Olympic gold, dominates the fall season winning back to back masters in Shanghai and Paris, becomes world number one, wins the WTF and then win the year ending number one trophy.
When you look at these accomplishments, he has ticked almost every box, and it is because of these insane peaks he has produced, on top of the incredible consistency, that I don't put him with the Wawrinka's of this world. For me, he might not be as great as Federer, Nadal, Djokovic, but if there is a big four, which for me there is, no one deserves that fourth spot more than him.
