normally i'd agree but norf don't have a best defender, do they? lol
one good thing about playing him would be the opportunity to play him into form, and to see how he fits structurally especially in a game we should win either way. only problem then is if it fizzes it's a bit hard to drop him after 1 game
so, i'd rather wait till he's banging down the door and there's an obvious replacement (for whatever reason....form, injury, etc)
