Looking at the replay, it seems like Renshaw was more using his head to keep Dean from forcing him into the barrier. Doesn't look like a major infringement. I know I've not raced, but if someone was pushing me towards the barrier at speed, I'd get a bit arsy too. The second offence where he looks left and then moves left onto Farrar seems worse. But does the punishment fit the crime? Seems harsh.
And from last year we know that Cav can win stages without a leadout, but that was then. Has he become dependent upon Renshaw now?
