The Channel 7 scorebug is nice in my opinion.
The Fox Footy one is weird.
Taking a second look and referencing what the NFL used for the Superbowl there's some similarities to the NFL and the Channel 7 design. The NFL one is wider but has nice wide margins between each stat box so you can still see the action. The Channel 7 design is small enough to not block most of the action and conveys the score and time left very clearly. I think the design will catch on even if people hate it now.
The Fox Footy design is bad. It should be rolled back. Why is it so big?
