It's an interesting one. As far as clash strips go, our's is one of the better - in that you can look at it and say, yeah I suppose that still looks 'Richmond-like'. Though I'd still much prefer to see us wear the traditional strip, just with white shorts.
The Adelaide clash strip though - the white one is bloody terrible. One thing with Adelaide, as far as expansion sides go, they actually came up with a pretty good jumper. Looks like a traditional footy jumper right from day one of their existence (I assume they just looked at the Central Districts jumper, said yeah, that looks pretty good and put SA state colours to it). Can't understand why they'd go for a horrible generic white strip when white isn't one of their colours.
Why don't they just have a predominately red version (where the navy and red are simply reversed) and a 3rd predominately yellow version (where the navy and yellow are simply reversed) as alternative strips. Make it look 'Adelaide Crows like' and don't change it every *smile*ing season so it builds tradition in itself.
If clubs must need a clash strip, just go minimalist, reversing the colour scheme and stick to that one version without changing it every season. St.Kilda are another interesting one. They've had some good 'least worst' options. One was their heritage barber shop number. Another was basically just making the black back, white and wearing white shorts. But then they change every bloody season and for no good reason try and reinvent the wheel and come up with some shockers - this season's for example.
