This isn't the same thing at all though. The sin bin is an event that isn't likely to repeat itself and therefore shouldn't be considered when evaluating a players worth.
Yeah hipdrop sinbins are pretty much becoming the new HIAs that are a random event that everyone is susceptible to, except they come with a negative on the stats.
I think what Brandy is talking about now is pretty onto it though. If you're Mam, you're a little half basically getting dragged along by a strong forward and just holding on and sliding down his legs, wtf is he meant to do. No player is trained to think oh one on one tackle and I'm sliding down guess I'll just let him go. That's not how tackling works.
It's not the same as the initial tackle that was a problem where you already had one or two guys holding the runner up and then someone tries to leverage their weight to take the legs out.
That Haas one RCG ends up in an awkward as fuck position with his legs spread apart like that. Then you put 120kg on him, yeah your groin is probably going to have a problem with your legs split like that.
