Or the 'right' offences properly targeted.
Yes I know there is no such thing as 'Ball to Hand' but some of the calls in the WC were ludicrous...2 players go for ball, the attacker heads it...on to the hand/wrist/forearm of the defender...it travels 18in max. Somebody complains, the Reff checks - yes it did hit his hand - mucho deliberation - Penalty!...technically.
For me VAR is there to tell the Reff that, yes he did see what he thought he saw.
Not to, after the event, via the imput of an aggrieved party...and at any given time 50% of the players on the pitch Will be aggreived...tell the Reff he was - in the old MrEnroe style - SOooo wrong; you can not be serious. etc, etc.
Nor will it make all these poor Reffs better, it will just give them more oportunities to do what they do most of the time now...get it wrong in the big boys favour.
