So the only sensible options at 12 would be Tele'a or Clarke. They'll likely put Tele'a there, but, personally, I want to see Clarke given a go. IIRC he has a desire to shift into the midfield, and now seems like a pretty good opportunity to give him a sneaky go.
This is, of course, assuming they don't just go all in with something bonkers like sticking Akira or Sotutu there. Though I would pay good money to see either there because it's either a complete no holds barred line/jailbreak time or silky smooth skip passing (of Rieko) time.
