Here's a suggestion to get all your knickers in a twist
I am a great believer in Gibbo's mantra "You pick your best 13 players and find them a position".
If we assume Iongi is playing fullback (maybe not from the season start), Moses and Brown stay where they are and we pick up a serviceable hooker (Hands maybe the best we can get), where do we play Gutho?
He is far too good for 14. Playing 13 or 9 (middle) will kill him (besides we have Hopgood, Matto etc to fill those roles).
Why not play him on an edge (preferably with Brown but could be Moses)? I can see him sorting out our centre/wing defence on that side with a few well chosen words.
