How is this wrong? And why is it even a tactical ploy? And why is tactics a bad word, even?
A batsman gets given out LBW, asks for a review, and it's shown to be missing the stumps. The decision is reversed and the batsman continues on. It may not be a howler, but an incorrect decision has still been overturned.
If the LBW is marginal i.e just clipping the stumps, then smart players will not ask for a review. Yes, there are the Watsons who review everything, but in most instances you will see the batsman talk to his partner and then walk off. If the player does review it then he wastes a review.
What is wrong with that? It's either out or you waste a precious review.
I think it was the NZ-RSA match where there was no reviews at all. Yes, umpires made correct decision, but there were also plenty of close calls that could have been reviewed but weren't. I think the players can get some credit as well. They weren't trying to get one over on the umpires. Maybe, just maybe, players want to use UDRS to overturn wrong decisions?
Manipulating technology? Pffft, they aren't jedi ffs.
Oh, and I'm so over the "oh noes, umpires are getting embarrassed" crap.
