Mark Cavendish, the best UK cyclist?

We've been through this before.
If Cav is up there at the end he can win. The last 1KM leadout isn't as important as people seem to think. He has proved he can use other riders and/or force his way through and win regardless. If a race is set for Renshaw to be able to win, then it's set for all the other sprinters too, and who's the best? oh yeah, shorty.
The question is can Sky kill the breakaways whilst keeping a steady ship for the last 10-20k?

You guys are missing the point. It's not just about a leadout train, it's about who the team focuses on in each stage. There's far more to securing a sprint win than then last 5k and obviously same goes for trying to secure GC places. HTC were there ONLY for Cav. Sky will not be.
