I also don't want Doueihi in the 13. His play style suits an edge, not a middle. Backrow, centre or 6 is all fine. 13 and 7 in my opinion is not.Thats if doueihi makes himself available to be picked at 13. Averillo at 5/8 has some kind of appeal but him and Taylan in the centres would be good.
For mine, he is likely the starting 6 but may be utilised elsewhere depending on other moving parts in the team. If he refuses he can either be sacked for breach of contract or play centre in reserve grade until he loses any value in his next contract.
I've no interest in Averillo at 6 either.
