Going by some of our previous full backs, yes Dummett's not great as an attacking threat but at least he can defend which is more than you can say about the like of Premier League winner Danny Simpson.
Eh? Simpson's defensive ability is all he had going for him. He's a bit like Dummett in all honesty, not too bad defensively but absolutely terrible with the ball. Likes the same floated ball to nobody in particular as well.
