Yes, some fair points there, they do have a bit of arrogance about them sometimes. To me though, there is a significant difference to US postal; US Postal turned up and we're suddenly better than everyone else for no apparent reason other than the obvious (and I know I'm saying this with the benefit of hindsight!), but Sky have changed a fair amount about the way teams ride stage races...
Things like using skinsuits on road stages and having proper warm downs after stages were unheard of before they did it; all the other teams laughed at first and then followed suit when they realised that they were actually on to something (and those are just two examples).
Obviously, none of this tells us if they're using PEDs, but to me they have earned a little of that arrogance and it makes the idea that they are clean quite a lot more credible than for Lance back in USPS days.
Gees, I'm starting to sound like a Sky fanboy here!
