Here's why I think it matters:
The Sky team was formed by David Brailsford with the express intention of going for a win in the Tour de France.
He tried to get sponsorship from the City, but got nowhere. BSkyB agreed to sponsor the team because James Murdoch is a cyclist; James Murdoch is no longer in charge at BSkyB because of the phone hacking scandals.
So - not a lot of UK corporate interest in cycling (of course, that may change now) and the team only exists because James Murdoch is a rider himself.
Having got the money, could Dave Brailsford, who, lets remember, is the head of British Cycling, with a string of Olympic medals, get together an all British team to support his three British stars (none of whom were born in Britain - pertinent to us here!) No - he could not find enough British riders to make up the six domestiques and had to get people from elsewhere.
Which tells me that there's a problem - Britain has three brilliant riders but just not enough strength in depth.
I hope this can be overcome soon.
