I think a brighter kit can help lesser players spot a team mate running off them, so helping peripheral vision.
But I think the main problem with team performance, at the moment is more to do with chemistry, than kit colour.
The chemistry that exists between Furman and Wes, that allows them, together, to equal far more than their individual talents should add up to.
I think PD has built a team around these two and because of a terrible piece of bad luck, it has completely upset the balance of the team.
Furman and Wes together compliment each other and allows for forward motion, as is shown by the fact, that when playing together we invariably win and one of the two invariably scores. A bit like tank treads if one comes if off yer bolloxed!
