Clearly the big signing (or 3-4) is required, but the injuries were a killer this year. If they had everybody available in 2022, there's a very decent/competitive 23 there. And some of the guys leaving have little reason to stay to be honest (e.g. Powell, Hardwick).
If all fit, they could have had:
Gibbon, Uelese, Pone, Philip, Hosea, Kemeny, Wilkin, Leota, Tuttle, Gordon, Anderson, To'omua, Kellaway, Magnay, Hodge.
Hanson, Orr, Eloff, Hill, Wells, Hardwick, Powell, Vaihu
Experienced depth leaves out Ross HP, Worth, Sorovi, Ioane, Tonumaipea, Ili, Nu'u, Ma'afu
Young talent leaves out Ripley, Jooste, Canham, Vudogo, Tuqiri, Van Nek, Kailea, Nowlan, Icely, Maiava, M.Gordon, Wallis
And then you've still got Skelton, Pincus (both unseen at Super Rugby level)
Maybe not a Super Rugby winning squad, but 'barely field a Super Rugby quality XV' is bullshit.
