Ireland head to Edinburgh this weekend and it’s my favourite time of the rugby year. I’ve always loved the Six Nations and it was certainly the highlight of the season when I was playing. The autumn internationals are great but they’re one-off encounters. The Six Nations brings with it a sense of tradition and history, away days in great rugby cities, fans mingling for days either side of the match and – most importantly – there’s a trophy to be won at the end of it all.Scotland are first up and like every game of rugby that’s ever been played, the battle will start up front, where we’re probably in as healthy a state as we’ve ever been. Sean Cronin’s injury leaves us a little shy of experience behind Rory Best at hooker but we’re in great shape in the props and the back five will be full of serious operators. In the back row, CJ Stander has been great for Munster, Jamie Heaslip is playing as well as ever, Josh van der Flier has been brilliant for Ireland, Sean O’Brien is back, Peter O’Mahony is back ... at least one of those players won’t be in the match-day 23 and it’s a great position to be in.
