No it's not the first sign, and it appears clear to me that there's serious discontent. And has been for a while. If they've been unhappy for a while and all the while RG keeps getting endorsed by the board etc then I'd be really starting to think, 'fuck it, I'm off' if I was them.
The thing is, some of them will be fielding offers from teams like the Brumbies, Tahs and Force and also overseas.
At the moment they have no certainty about what is happening at the Reds.
A lot of them would possibly stick around if a good coach was appointed but the door will likely shut on other likely good or at least palatable offers before they know who might be the next coach.
I know what I'd be doing in that case and that's what worries me.
