This could be a speculate to accumulate move from the club, one I'm surprised they haven't taken before.
In recent years they've had their fingers burnt with regard to kits. Poor quality shirts (a shame, because the design isn't bad at all) this season with an excessively high number of refunds. There was also of course the Jako efforts of a couple of years ago that were poorly made and in the case of the black away shirt, drastically late at the start of the season which must have impacted negatively upon sales.
This decision though looks different. Like it or not, a Puma shirt will excite a fair part of the target audience for replica shirt wearers far more than a Burrda, Joma or Jako effort would. We may well end up with an off-the-peg design such as Cardiff's home shirt but the fact is it will be made by a manufacturer that carries a reputation for quality, a name that will undoubtedly boost sales and in all probability an aesthetically pleasing design. I'd be more than happy for example with a royal blue of Coventry's shirt, understated with a touch of the retro.
