Never understood why the ref calls held 5 times, and then Scam hangs on for 3 more seconds and uses his elbow on the tackled players neck to stand up and the ref is all "nothing to see here".
It's a joke.
Th pandomine and theatre of the pocket ref running in and melodramatically bending over and pointing at them is also a thing of beauty ... useless and ignored .... but I guess it makes them feel important ....
