How many times did Quartermaine call B2 Joel? Worst caller going around.
The problem with/for interestate commentators is obviously the hometown bias. The difference is that whenever they are on air they are commentating a hometown team and they only see and commentate the other teams once a year if at all so by definition they will be unfamiliar with the visiting sides players, set-up and gameplay.
In Vic, Rex et al are biased to their own teams but often they are commentating other teams and they get to see all the teams reasonably frequently and are familiar with names (well maybe not Rex "gets it out to the player in..... uh....and he gets it out to") so the bias does not manifest as badly.
Its something the ABC in particular could address because some of the interstate guys are good callers they just don't get the broader opportunity.
