Yes you can. Nobody's house is 'squeaky clean'. If you've never had a crack at a ref before then I doubt your capacity to feel emotion at all. You'd be a sociopath, someone not connected to humanity, likely with an ever-growing pile of corpses in your basement.
If only the uncompromised could comment on here then it would be a very lonely place indeed.
I support refs, but I also allow for the occasional demonstration of frustration or emotion. These games matter so much to the players and coaches, and so if the difference between winning and losing is (arguably) a few questionable decisions then it's not shocking that bubbles over in the immediate aftermath of the game.
Once the emotion bubbles down I'd hope Rennie would be a bit sheepish. And that's where Rassie went beyond the pale - at the moment he should have backed down (or at least shut his mouth) he doubled down. And then he doubled down again. If Rennie did that then I'd be leading the charge with pitchfork in hand.
Fair enough Barbs, we will see if Rennie and RA say something to calm down, I not so much thinking Rennie is all that wrong but RA should say something along lines we don't agree with Dave for saying it or something. Once you put a flag in the sand you have to go kind of stick with it. I not suggesting he has done a Rassie, but from what I see RA by not saying they not comfortable are saying they decide how far coaches go.
All it looks to me is you can't get stuck into our refs, but we will be quiet if our coach wants a crack at others. Apperances maybe wrong , but how it appearing.. And no I haven't has a crack at a ref on a public forum, and I do get frustrated, but decided many years ago while coaching kids you can't get shitty and yell at refs etc, and then say to your charges that you have to do as ref says.
I know old fashioned as buggery, but what I believe.
