Here's my thoughts on this and all other extensive TMO enquiries, echoing exactly what Tim Horan said on The Breakdown rugby show in NZ earlier this week.
We sit watching Super Rugby on SKY Sport NZ. At the same time on other channels you have a variety of sports, including live Rugby League and Aussie Rules. When a rugby game is stopped for five minutes of replays, searching for foul play, I go to the remote and change to a sport which deals with similar in a far less time consuming manner or (in the case of AFL) after the game is concluded.
Say what you like about Aussie Rules, it keeps moving. When a goal is scored (unless they think it touched on the line), it's a goal. Celebrations are immediate, no TMO, no VAR, etc, and that for me makes it the best winter sport going around.
