Can't see past France from a NH point of view. I think they're the only team with the real quality and experience all over the park at the moment - extremely unlikely they can be arsed to win it though.
England are a potentially very good side 2-3 seasons from now with a bit of fortune in a few positions, and when they've stopped picking turkeys like Hape and Bananaham.
Ireland, too inconsistent. Wales' current 1st XV is pretty smart but I don't think they've much depth and they seem to be a bit up their own arses at the moment.
So in conclusion, no.
