I thought it might have been an OG at first, but what a touch.
The winner was a thing of beauty, absolutely chuffed for McLean as he's usually brought on to run down the clock.
ETA: I think Gilmour made a difference when he came on, as while McGregor is neat and tidy in possession, Gilmour played on the front foot, tried to make more positive forward passes and pushed us up the park a bit.
