For the past 7 or 8 years, Channel 7, the local broadcaster has had Jim Courier as its prime commentator for the AO. Before Courier, they had John McEnroe, for 1 year I think, and as interesting as he was as a player, I just found McEnroe as a commentator boring and old school. I was never a fan of Courier as a player, but I must say, I find his commentating very insightful and he's very well versed as far as the AO is concerned.
