I have to agree with a number of comments already posted.
I thought the coverage was a disgrace and as far as I can be certain she's a lovely person I'm afraid Johanna Griggs is not the person I want to see grinning/giggling back at me every time I flick to Ch7 to view its meagre offerings.
Is she the network's female equivalent of Ch9's Eddie McGuire or what?! How many shows does she host/appear in? And really, I'm not sure her talents as a commentator are proportional with her degree of exposure.
Just my opinion. Probably a mile off the pace.
