Whatever one thinks of Foster you have to say he's building some good quality depth in positions that were considered problematic not so long ago: hooker, six & midfield.
Coles will be 37 in 2023 & I'm not sure he'll even be still playing but if he is I think he'll be the injury insurance. By then Codie will be at the same career stage as Coles is now (hopefully minus the injury issues) & even he may struggle to get game time if Samisoni, Aumua & Eklund continue on their current trajectories.
We now have two proven Test-ready sixes in Akira & Blackadder & possibly a third in Grace (we should find out one way or the other this EOYT). At this point I think we can safely move Frizell & Squire into the injury insurance column as well & not even think about playing ScoBar there again except in an extreme situation, nor converting Vaa'i into a six.
Quinn Tupaea has come a long way in a short time & you can no longer say he's just holding Goodhue's place. I can see him becoming a long-term, best-XV player as early as next year if he stays injury-free & gets given the opportunities. Probably at the expense of Ennor.
Problem areas for me remain lock (Vaa'i is a potential great imo, ScoBar & PatT are serviceable but really need to be playing either/ or alongside SamW or Lurch, not together/ instead of) & 5/8: there's some talented kids around but they're kids, 2023 may be a RWC cycle too soon for many of them. If DMac is still considered our third-best 5/8 in two years time I think we've got a major problem. Really need at least one of the younger guys to have a breakout SRP (Super Rugby Pacific) & demand inclusion in the 2022 EOYT squad if not sooner.
