"How many people does it take to get things right? We have four officials now and people sat in the stand monitoring what goes on and there's still some bad decisions being made." he said.
The Millers boss could undersand Palace Manager Niel Warnock's anger, adding: "Watching the match between Bristol City and Crystal Palace last Saturday, anyone could see that Freddie Sears shot the ball into the net. Apart from anything, it came out at a different angle than if it had hit the post. I could fully understand why Neil Warnock was as angry as he was and if that sort of thing had happened to me I would have gone mental.
"The decision cost Palace at least a point and it's mistakes like that that could cost a manager his livelihood. I'm not saying things like that haven't happened before, because they have. We all remember the "ghost goal" between Reading at Watford last season.
"I think that at ice hockey they have a buzzer that sounds if the puck hits the back of the goal. I'm not for having light and other paraphernalia on goalposts but if the technological decisionmaking process is quick and it is brought in across the board at our level, I don't have a problem with it."
