Ireland and their fans went into half-time at Murrayfield somewhat in a state of mild shock. The Scots, fancied by some, had three tries on the board to Ireland's one as they led 21-8.
On BBC, Paul O'Connell felt that three aspects of Ireland's game, in particular, failed them in the first half.
Ireland have a plan that they haven't really stuck to. One of the big things that has been successful for Ireland in the last few years has been the set piece, the lineout has been excellent and they've always been disciplined. They generally win that penalty count. They don't give away silly penalties.
You look at the lineout that was turned over for the first [Scotland try], you look at Simon Zebo going to the floor and not rolling and rotating and not doing his best to get the ball out.
The other thing is the five-metre drives. Ireland have been very good at defending five metre drives and they've been very good at converting.
Today has been the opposite in many respects in the lineout, discipline and five-metre drives.
Over on RTÉ, Ronan O'Gara thought Ireland were being bullied by the Scots and that communication in defence was also failing Joe Schmidt's side.
I think Ireland have been bullied with the ball. We've been inaccurate. I think the third point would be we need to sort out the backs' defence. There's a breakdown of communication or trust between players that haven't played together at that level.
Hogg is getting too much of a free run. A good player, yes, but he shouldn't be made to look that good.
Here's what ROG had to say.
