I agree, I thought that Collum was having a good game up until that point. To be fair to him, he's not that bad but there is often a turning point in games when he completely loses the plot thereafter. The stramash could have been it on this occasion, especially as he bizarrely played on with two balls on the pitch straight after and I was thinking.... Oh no, here we go, he's snapped again.... But he kept his shit together.
