Coaches challenge for the Griffin try would still be cancelled off because they aren't even applying the rules correctly.
Even Cummings said he (Ablett) was nowhere near the play so whatever minor interference would not have changed the outcome as was drawn to the dummy runner and too far away to do anything.
Running it at slo mo is just stupid anyway as that's not how it happens, it would clearly show Ablett would need to make 10 yards in 1.5 seconds from a standing start. Not even Ben Johnson doped to the gills could do that!
Even Ablett nor any (many?) Leeds players throw up their arms which is a sign even they didn't think it was obstruction.
Coaches challenge is fine in theory, the main problem is the decision making of the officials, in Australia that would not be chalked off and definitely not at the WC
