Rugby's a fun game at times, isn't it.
Those comments came about since the Highlanders managed a couple of breakaway tries within about three minutes of each other, but the Brumbies had probably looked the better side for most of the half (I think they missed at least three penalties in the first half alone which would've put them ahead). Plus the referee had just warned the Highlanders that they were conceeding too many penalties and would be yellow carded if that continued, so those comments were fair despite the scoreline.
Either way, very pleasing to see the Highlanders take the victory, and I imagine particularly so for Southland fans with all three tries to Stags players.
