Top 5 DRS decision that changed the course of a cricket match

#4 Rahul Dravid vs England Birmingham, 2011

Rahul Dravid walks out without reviewing his out call

This was the third match of India's forgetful tour to England. Rahul Dravid was the only batsman who was amongst the runs. He was facing James Anderson in the second innings, and Anderson was making the ball hoop around.

One such ball was an absolute peach, as it shaped in and the seamed away to beat Dravid's prod. Matt Prior took the catch and umpire Simon Taufel gave it out. Dravid decided not to review the call, and walked away. However, when the replays came up, it showed that the bat had clipped the shoelaces, and was nowhere near the ball. This was the reason behind the noise, and only if Dravid had reviewed, he would have remained at the wicket, and India could have saved the Test.

A case of DRS not being used at the critical time.
