Benetton could, but Castres at home have a tendency to be annoying as fuck to beat, and I’d be surprised no matter how well the former appear to be doing in the UrC.
Clermont winning away also wouldn’t be the biggest surprise ever, but I’d still not be putting money on them.
They did similar round here. Now people park on the road and, as a result people drive their cars on the pavement. Would be nice if they actually slowed down while doing so, mind.
I certainly wouldn’t bet on it, but recent history would tend ti agree with my original quip.

(When I made my initial joke, I actually hadn’t quite really realised just how close they’ve come or how regularly)
