3.I think they are trying to say is that they don't want to be a logo or brand on a football team because maybe they don't like football.Or there just not comfortable being as mascot.And they probably feel mocked being in a football name.
4.I think it's nice I don't really care about football.The way they make the message is really convincing.If they dont want to be in a mascot then it's there choice to be or not to be in it.
