Why is it now a case that one head-buts when it happens? (i.e., why is it such a big deal that Dean "threw the first punch"). Is he allowed to throw an elbow, but others can't?
And in any case, I don't think any elbows where thrown to begin with. Dean was just trying to get in on his line a bit to stop him from passing.
Leaning in/shouldering are normal in sprints. Renshaw said just that after stage 5: '"There was a lot of shouldering," said Renshaw after the stage, "but that’s the sport."'
