I hope you're not assuming I'm one of them?
As for the team, why are the same suits vital? Has it moved the sport forward in the UK? I think that's open very much to debate.
Fans need to see the personalities of the riders - this can be achieved in many ways of course - Doyle got my attention with his sliding around the stock car track, Cook with his riding style but mainly attitude and antics outside of the races, John Davis/Havelock/Wigg with their leathers and branding, these are things which draw interest and create taking points, not them all wearing the same suit, I really don't get the point of it, they'll be riding for another team next year. The race jacket was enough.
Why do we need helmet colours these days? The suit and number is enough surely. It's all window dressing for a photo but that doesn't bring fans in, engagement does.
