Like I already said, this is my personal opinion. Barely any of those 7 hundreds (from the one's I've seen) have come in a pressure situation while most times Rahane and Vijay scored, India was struggling. Cricket isn't a game of statistics primarily.
Sure, I was responding to the "If you're speaking of Root, KW and Smith then let me assure you, there is no confusion in the fact that they are ahead of him while Smith is in a league of his own" part.
