It is just a small part, but I do think it can be discussed as it contributes to overall stereotypes about both Oxbridge and rowing, and that's important in terms of their campaigns to increase diversity. Spraying champagne is a part of some sports, yes, but as part of a celebration, rather than a photo op in itself, I think. You can still question traditions and adapt them as times move on. I don't blame the teams, either - more the way that the sponsors are setting up the event, and the impact it has on the work that is being done to change stereotypes.
I don't think talking about it distracts from the amazing sporting achievements, either, which were superb and also worth talking about. Both excellent races, and I learned a lot about how the cox's decisions can be crucial, which I'd not appreciated enough before. It was fascinating hearing the commentary about the choices the cox made, and how they were surprised at the boldness too. But it seems to have paid off! I wonder how aware the rowers are of the decisions that are being made or if they are just so focused on their job, and trust the coxes so completely, that they don't think about that aspect of it.
I wonder how the Oxford chap is doing. I remember a few years ago there was a similar sort of incident, with someone collapsing towards the end. I can imagine how giving your all for that amount of time could cause a medical issue. The heart rates that they are monitoring and show on screen sometimes are incredible.
