Gareth Batty, Surrey's coach, has compared the County Championship's two-week trial of the Kookaburra ball to telling teams to play with ten men or changing the shape of a football midway through the Premier League season.
The experiment, which saw the Kookaburra ball used instead of the standard Dukes over the last two rounds of county fixtures, was recommended by Andrew Strauss' High Performance Review, commissioned in the aftermath of England's 4-0 Ashes defeat to Australia in 2021-22.
The review said that the trial would give the ECB "a firmer understanding" of the difference between the two balls, suggesting that using the Kookaburra instead of the Dukes could force "the development of a wider range of skills" among English seamers and enhance the role of spinners.
But Batty described the trial as "very silly" and "a kneejerk reaction" to England's defeat in Australia. "It's like saying next week, we've got to play with 10 men," he told ESPNcricinfo. "That seems silly to me. We don't change the shape of the ball in football halfway through; we don't mess up what is going on."
Speaking after his Surrey side drew with Nottinghamshire at The Oval, Batty said that the timing of the trial was "illogical", citing the possibility of players being called up for England and using a different ball to the one they had been using in domestic cricket.
"If anybody were to be called up from county cricket, bowling with a Kookaburra ball, it makes no sense that they're having to change to a Dukes ball," he said. "There are different characteristics to the two balls. I like them both equally. I'm certainly not criticising the fact that we're using it but the timing of it is questionable."
Peter Moores, Notts' coach, suggested that the competitive integrity of the Championship was undermined by the trial. "I don't like the thought of mixing up balls in a season, because it doesn't feel right," he said. "If you start with one ball, I'd like to use it [throughout]."
Moores added: "I can see exactly why the ECB want to test it out and have a look at it and how it's reacted… generally, the Dukes ball is a good ball but over the last couple of seasons, it's tended to have to be changed a bit too much for me and that's something we want to try and get away from because as a ball gets older and deteriorates, that's when spinners come into the game.
"I think the [Kookaburra] ball has played pretty well on the pitches we've played on. We played at Taunton and we played here. Both pitches had a reasonable covering of grass which I think helped movement and kept carry in the ball. The ball didn't go out of shape, which I think is a good thing because it brings spinners into the game."
But Batty insisted that he was unclear why the trial had been introduced, and that if the intention was to bring spinners into the game, it hadn't worked. "I wasn't privy to those meetings," he said. "Nobody has asked - from what I understand - anybody that is in a position at counties to evolve and create England players [about it]. That seems strange.
"Does it bring spinners into it? I don't think that it looks like it has done across the counties. There's a few counties who have made pitches very dry to try and bring spin into it because they feel like the ball won't move laterally, which is absolutely fine and I totally get that. That's a positive, both for batters and spinners."
Batty cited the decrease in the number of points available for a draw - from eight to five, compared to 16 for a win - as evidence that English cricket wants a "quick fix" when it comes to creating spinners, rather than clear long-term thinking. "The points system has negated spinners this year," he said.
"Let's say it as it is: everybody is playing for wins and losses now. A draw means less than it did last year. We have changed as current champions how we think about the game because of the points system. Everybody needs a quick fix because you want to win; unfortunately, you don't get a quick fix with spin."
