I don't know if he'll win, I'm not great at predicting the general overall public opinion on things (I tend to go against it most of the time, so maybe just because of that he does stand a chance of winning).
It's nice that Rob is trying to be a bit more rounded though in his dancing and trying to show he can diversify a bit more than just going down the weekly comedy route. He can actually dance to a degree, so it's good he's not wasting this opportunity to actually learn to dance and experience it as a wider artistic and emotional form and not just something for laughs. If comedy was the only realistic target for him then fine, but he's beyond that, so should aim to improve because he can (even if in small amounts to the likes of Danny, Ore etc).
