So recently, there has been this incident where a batsmen was out due to a mankad (http://www.news.com.au/sport/cricket/cricket-greats-slam-mankad-dismissal-at-u19-cricket-world-cup/news-story/e4134bb470e2482f0a17dc4dedba6c1f)
Having read what it actually is, I don't really understand why it's against the spirit of the game. I mean, it's a legitimate dismissal within the rules of cricket and it's fairly easy to avoid being dismissed this way by just not trying to leaving the crease to get a headstart before the ball is bowled.
It seems to be the cricket version of getting out while trying to steal a base (in baseball). Why is there so much outrage about it?
