I think he is sellable, at least as much as any fit scoring player is. Ideally he isn't final a 17 player, but with recent injury carnage almost nobody is looking at ideals anymore, so I guess it depends on remaining trades and the rest of your team
He is someone who I will look at moving on once I complete my WFB. Next week Teddy is essential, so 2 of Luai/Rudolf/Drinkwater/HTF will become cow and Teddy.
I will then be able to relax for a while, barring injury, before I look at my Lucy’s, Carrigans, other cows to just beef up my other stocks.
