Cricket is such a stop-start game anyway, that I don't see how video replay can really interrupt the game to any significant degree?
From my point of view, every single appeal should be referred to video review / snickometer.
With the technology available today, there's no reason why umpires
shouldn't be reduced to glorified coat stands.
Being serious, they can still run the game, they can still check on the match ball, they can still enforce fairplay and adherence to cricket's rules..... but they shouldn't be making critical decisions based on
their opinion of events.
