So, to the fourth weekend, when a few things will be decided...
Ireland-Italy: I reckon Italy were a bit stunned by the last-minute loss to Scotland, as that was their "must-win" match. But I'm likewise stunned by the decision to drop Parisse - I can't recall them ever doing that before. Sexton's been passed fit after a scare, and should be a reasonably comfortable win for Ireland, in BOD's last home international.
Scotland-France: Scotland buoyed up by their win in Rome, unexpected by most. France's team selections look frankly weird - either brilliant or reflecting that they've gone into a panic. May be tight, but I think Scotland could just sneak a win.
England-Wales: Should be the match of the weekend, with so much recent history (as well as ancient history!) behind it, and a few crunch onfield battles. Didn't manage tickets for this one, so will be watching on TV. Result's too tight to call, I'm not going to attempt it.
After which, it should be down to two possible winners... was reading yesterday about the 1973 5 Nations championship, which ended in a five-way tie. I just about remember it.
Hope you had a good St David's day, Aled.

Likes the warm feeling but is tired of all the dehydration.
