There's only two looseheads in our 6N squad so it's hardly absurd.
Don't think that sounds bad at all really, certainly neither Ringrose or JO'D are ready for test rugby yet. Just throwing all young players in rarely works either. I expect the progression to work like Henshaw's. He was involved in training squads and off the bench a few times. Then when he needed to start he was ready and at 22 looks like he was born for test rugby, I don't think it would have happened the same way if he'd just been thrown in. The only players Schmidt mentions by name who are actually in the squad or Dillane and VDF who I think definitely aren't ready to be thrown in either.
Notably the young player he doesn't mention is McCloskey which suggests he might well get a go and he is the most test match ready of the younger players. I didn't talk about Stander because he's 25 and is guaranteed to at least be in the 23.
