The opinion didn't change. He was picked off the back of a handful of great games (after a few shockers), at a very young age. He was always a risk, and a borderline pick.
His first game was okay. Not outstanding but he did nothing to warrant dropping.
The second, on the other hand, was a shocker. He made 2 tackles, missed 5 with 1 ineffective. And made 4 errors. That's more than enough reason to get dropped. You can't do that at Origin level. That's probably an Origin record.
If that were Xavier Coates, the air would be blue with insults calling for his head, and him never to play Origin again. But it's Selwyn, and everyone's being pretty kind about it.
