Same for both sides though. Not sure a painted stripe down the middle would necessarily make too much difference but it'd be interesting to find out. The more I see a gaggle of players huddling together to debate an umpire's decision, the more worried I become of the effect this is having on the game. Seeing players openly question the umpire isn't cricket and anything that can be done to return some authority to the umpires would be alright with me.
There must be other things that can be done to help? An automated system for no balls perhaps so the umpires aren't having to look up and down?
