Assuming he returns JJBM easily stays on bench or in above scenario may well start over Felix.
Unless Jets bring in someone their bench could use a lot of the most Cup ready couple of Araullo, Challenor, Sele, Dellow, White, Vito
You'd like to see a couple get a few chances, but like you say, a lot might be more than they are quite up to yet (happy to be proven wrong!)
Coutts left as I recall as the other inhouse second rower that could have possibly taken that spot. At the moment it appears to default to Hosking, especially with Puru and McCullough as locks already. Again though, could bring someone in. Leiu would have been good to keep here as a starter second row or experienced bench forward option.
