Fittler is insightful, unfortunately he's also the class clown. The best spot for him is on the sidelines adding the odd comment here and there.
I actually believe that the nine commentary, apart from the three main callers Rabbs, Raaay and TimTam has improved this year.
Gould has toned down his arguing and cliches.
Sterlo remains an excellent analyst and Joey has improved out of sight as well and is up there with Sterlo.
When Wally and Lockyer are commentating on non Bronco games they are also very insightful.
Freddy and Finch belong on the sideline, they bring good insight and humour but should only be used in small doses.
