If the experience of the past few weeks is anything to go by, a spectacle it won't be.
The first weekend aside this has been one of the dullest - probably the dullest Six Nations ever. Alan Quinlan in the Irish Times did an analysis of the offloads (passes out of tackles) per country and the stats are very depressing. Ireland in particular have an abysmal record in that respect, although we seem to have played most of our matches in either a hurricane or a downpour, which doesn't help, and have had 27 injuries or suspensions!
Wales ought to win, but who knows.
