The forgotten men - the umpires. How come they can't exert a bit more authority over how the games are played? They only seem to get involved in matters of dissent, or running on the pitch. They must hear all sorts of stuff that is likely to escalate tensions between teams. Can't they stop it, or at least report it after the day's play? Maybe we should have microphones as well as cameras, every player miked up .
The umpires have become nothing more than coat hangers. So many of them are ex players. They know how quickly things can get out of hand, but seem so reluctant to put an early stop to so much of this garbage that goes on out in the middle. This goes for sledging and slow over rates. Umpires used to be far more proactive. (No, not everything was better in my day) !
Maybe it is as they lose authority with the DRS, they feel less authoritative in general.
