Now to an off-field blunder of epic proportions. If you're going to film a Grand Slam champions TV advert, you'd better make sure you actually win the Slam first. Or, if you're so desperate to appear in front of a camera that you can't wait that long, it's probably a good idea to make sure the video doesn't leak online.
Unfortunately for them, the England team of 2011 heeded neither of these warnings. Their 30-second Nike ad was supposed to celebrate a famous Grand Slam win, England's first since 2003.
Standing in their way were Ireland and the newly-built Aviva Stadium. Predictably, England contrived to lose to the rampaging men in green and with that went Nike's chance of ever airing the ad.
Only, Nike failed to keep the commercial under wraps. It leaked onto YouTube and, to compound matters, details of 5,000 commemorative Grand Slam T-shirts to be sold at full-time also surfaced. This was all much to the delight of Ireland fans.
As Hugh Farrelly of the Irish Independent put it:
If losing the Grand Slam to Ireland was not bad enough, England have suffered the embarrassment of a celebration video being leaked to YouTube as well as thousands of unwanted commemorative T-shirts in the wake of Saturday’s 24-8 defeat at Lansdowne Road.
