First time seeing Elliot Bell in person yesterday. I can see the makings of a decent referee. He seemed to be a calm and composed figure, dealing with any flash points fairly well and seemed willing to talk to control proceedings.
All three cautions were correct, potential argument that the Wilmot challenge was in the orange category. For that Wilmot incident, he did have a discussion over the comms with his assistant before deciding on yellow.
Overall, a positive showing and can see why he's risen to this level quite quickly.
