I get why Melbourne are doing it tbh. Pap's obviously gone and while Sua has first crack, his defence has long been a bit suss.
If he cant nail it, Meaney will need to shift back there and with Grant gone as well, Melb are already light amongst the outside backs. So targeting Lomax is probably a smart call roster-wise.
Agree it still feels uncomfortable given the circumstances but that said... their first responsibility is to win games, and as much as Lomax is looking like a bit of a twat right now, he's not quite an oxygen thief like Mann or others of that ilk.
