The Golob and AJ exclusions were extremely poor decisions, especially considering the technology available to the referee. Both riders were deprived of the chance of higher point scores as a result.
They could both have been understandable errors, if he had not had the benefit of video replays. Whilst both incidents from ceratin angles could have been interpreted as Tomaz and AJ at fault, when seen from other angles they were both pure racing incidents, although Rickardson should have been excluded in his accident.
I think the referee rushed his decisions under pressure. If they are to use video technology, then they should utilise every possible camera angle available before making a decision.
