2 props and a backrower who can also play in the middle should fill the first 3 spots.
Ah Mau will be the first bench prop, then take your pick between Allgood, Latimore and Lawrie for the 2nd prop. Sims could conceivably take the 2nd prop role as well.
Leilua, Sele or Sims (if he’s not the 2nd prop) can fill the 3rd forward role (assuming Host will take over Thommo’s spot).
The 4th bench spot is a tough one. Ideally a back up hooker who can play as another running forward to spell McInnes would be handy (shame Havili is gone). As some others have said, perhaps we could try Sele in this role if he can’t crack another spot on the bench?
And whilst unpopular on this forum, I also wouldn’t mind seeing Field used at 17 with Hunt at hooker late in the game, particularly if we’re chasing points.
