We have other options for 13 and I can’t really see what Nowell’s USP would be there. Slade’s got a good passing and kicking game, Manu if fit has his power, Daly has serious gas and good kicking and JJ his defence (one day he’ll remember what a good attacker he can be too). Depending on how you want to play you might rank him above some of those at any one time, but probably never all of them.
And maybe like Slade at 12, he’ll look great on paper, but not be such great shakes on grass anyway. We just don’t know yet.
His pace rules him out as a starting wing for me. I think the 23 shirt is right when everyone’s fit. No shame in that, but much as I like him I just don’t see him ever as an undisputed first choice in any position.
