I was wondering about JDG having an injury and thought groin as his kicking has been way off.
If he and Mitchell don't come up, Elliott/McCreery in the centre and give either MacRae/McInnes full game the other sub.
Maybe even give the Sarge a go in the centre.
Time for the coach to think outside the box.
Doesn't explain his inability to hit a handball target 3 metres away.
