Overall I thinks WBs are looking decent, if not spectacular. Most of the young players are showing flashes of being test players and are making some errors that can be chalked up to inexperience. The depth at forwards right now is better than I can remember in recent memory. No more Timani or Simmons starting or being the first subs, no offense to them. There's very little drop off when subs come in.
As a former winger sometimes the ball just doesn't come your way and I don't think you can hate Petaia for not being more involved. The Kellaway try was obviously not on Petaia's side of the field and the kick through was more to Banks in the middle than outside where Petaia was hanging out. He needs some work, but what player in their early twenties doesn't? Same goes for Lolesio, Paisami.
Not sold on Banks at 15, he's a fine stop gap but ultimately I think you want a lot more from your 15 at international rugby. He's objectively worse than the AB's first 5-10 options and wouldn't get a look in at most international sides (Eng., France, SA, IRE, Scotland, Wales etc.). He reminds me a lot of Jessie Mogg in that respect. I think Hodge would have performed about as well today and would have done a better job kicking for touch. He's also a stop gap kind of player.
