This is my view. Why apologise when they weren't wrong.
I'm more amused the Scots don't seem to know rules. As you say the probability is it did go down but 100% clear evidence needed to overturn it. And like you I have yet to see this.
SRU should be the ones apologising for not knowing rules and looking for excuses.
@Saintjay I know this case well as brain injuries are what I have done extensive courses in from being physio in a sport like rugby. And the more I hear stories of SRU the more you nearly do believe they are very negligent and in a way fail in many ways.
The case you refer they were very slow to apologise and even then it was hollow enough. And in report above they are whinging yet still can't see what refs did wrong and then at end say we don't want to sound like sore loosers. But they are sounding that way and questioning refs for 2 weeks I think is papering over issues they have. Think Townsend has hit his peak there
