Not saying he would have gone out of his way to block DRS, but I'm sure his opinion would've been asked. You can see why he'd not want it. Can only benefit someone like Swann.
Look how KP had to change his game against spin once DRS was introduced. It ruined him for a small period of his career. He basically started playing everything from well outside leg stump on the back foot. If I was a batsman and could avoid something forcing me to change my technique or strategy, I'd avoid it.
So again dear sir, if it was so hard for India to win with DRS, that BCCI has to block DRS, or else India would have Tendulkar LBW, and then it would spread like an epidemic to the rest of the team, and the whole batting unit would turn into a bunch of senseless zombies who would forget how to use the bat and keep trying to kick the ball, to the point that not one batsman will be able to score a single run, all of whom would have been bowled LBW by Swann, regardless of which nation they were playing ... I have only one question.
If this ****** theory was nothing more than bullsh*t, then why has India one both the major tournaments which it has played with DRS? WC 2011 and CT 2013 - both had DRS, both were the two of the biggest ticket tournaments, and India won them both. Hahahaha
So how does this fit in with your theory that with DRS India just cannot win, and thus want to avoid DRS? Hahaha
