Couple of things on this, as I’ve seen it said a few times.Won the game because Hogg dropped the ball over the line.
Hogg dropped the ball in the corner. No guarantees Hastings makes that kick.
Scotland had a penalty advantage, which Hastings did kick over from in front. So the maximum difference the try would have made is 4 points, and possibly only 2.
Ireland scored 2 more penalties after that, and still repelled the on-the-line final assault from Scotland. And won by 7. I know some feel differently, but I never felt the result was in doubt on Saturday, and I think most of the reaction is an overreaction to us not beating Scotland by as much as some people expected us to.
I’m a lot more concerned that the gameplan hasn’t changed, than by anything performance related from the weekend.
