I'd leave Sultana in Flegg tbh. no doubt there needs to be some stability around some players and how they're developed (Mapapalangi, Mason and Luke Lau getting moved about case in point), but that's on Benji and Betsey. they need to be better at that for whoever is due in the seat next.
I think Sultana's strength is in identifying which players can be developed and transitioned quickly from SG to Flegg. those over 21 identified for higher honours will likely be training with the top squad and under the tutelage of the FG staff anyway. for that reason I'd leave him there.
additionally, I'm really curious to see who transitions permanently to Cup from this Flegg crop. having Broederlow, Saukuru, Roberts and Godinet all on the books means a couple will miss out, and Taupau-Moors will do well to lock down a spot on the pine pending what happens in preseason. nice to have depth, but again I have no idea what transpires.
Haywood will obviously push his way thru and Tavana will likely lock down the right sting in Cup, but I've got no idea where Liles, Mataale, Matai and Lanyon end up. less worried about the Taotua's, Delaney, Deninger etc cause they've got another year of Flegg to go.
