@Chris technically I suppose depending on how you define senior. Any of Lomax, Tungafasi and Tuipolotu are technically senior all blacks though all three have spent more time out of camp due to injury than out of it.
I suppose if any of Groota (Who I could see being pissed off if there’s inconsistency in punishments), Vaii, Clarke or Big Samisoni are kicking up a fuss than you’d think that would carry some weight too given they’ve all been around five seasons or more.
You’d have to think ALB & Reiko are both with Savea on this one too. Doubt Christie is speaking highly of his treatment too. That could be your four players. Maybe throw in Papalii & possibly Groota into the mix as having legitimate concerns and the deck starts looking uncomfortable for Razor. Though by no means impossible.
The real tipping point is if you get a few more players willing to join them. It would only take a few more voices of dissension to make it untenable for Razor or Hansen.
