Yeah, might be the case. People relate players with such iconic knocks.
'15 centuries in 250 matches' won't be the most imposing characteristic of the preeminent opener of his era. So many times he has looked good to carry on but has failed to do so. However, his cameos at the top were critical to India's success.
Case in point being the 2011 semifinal. India won by 29 runs and same number of runs was the difference between the scores of both teams in their powerplay; thanks to Sehwag. That knock made Gul useless for the rest of the match, made Afridi lost his confidence on Razzaq and put the whole opposition team under pressure. Moreover, other batsmen could afford to take time to play themselves in. And the most important thing, it provided India with the momentum to build their innings. Now in that match, they failed to capitalize the momentum and that's why they won by only 29 runs. In most of the cases, someone else from the strong Indian line up would make use of that start to go big and would take all the accolades.
He was a mighty effective opener for his team and up there with the best openers in this format.
