Bollocks he was. Kohli outscored him by almost 300 runs that series. 140 of them in an epic run chase that they would've won if anyone in the Indian middle order decided to stick around and support him.
Coming into that tour (end of 2014):
Rahane averaged 39.88 after 10 matches.
Kohli averaged 39.46 after 29 matches.
At the end of the tour:
Rahane averaged 44.87 after 14 matches
Kohli averaged 46.30 after 33 matches
By the end of the New Zealand series of 2016:
Rahane averaged 51.37 after 29 matches
Kohli averaged 45.56 after 48 matches
Rahane was also superior to Kohli in away series'. I think, up until this point, Rahane was the better test batsmen, however, Kohli has been insane since England home series and Jinx has been awful.
