There you have it. Most will already have an nfl hat of the team they support. Many wear them in the London games as a way of showing support to said team and also to keep their head warm.The Sunderland one's are cheap shite. The NFL one's are fleece-lined and warm as toast.
Was in the club shop last week and the hats are terrible and the nfl ones are more expensive and much better quality. Create a similar safc one and I'll wear it.
Also, if anyone really has an issue with what someone else wears on their head then they really need to have a word with themselves.
