I think most football fans like myself are football fans at heart in the purest sense. But most of us are fans of certain teams, players, or coaches. For example, in college Mike Leach was my offensive line coach. He is now the head coach at Washington St. I pull for them bc of him. I am a fan though of the Miami Hurricanes.
I think HurricaneFan.club would be better.
Now having said all of that, for the football enthusiasts among us football fan dot club could be a great place to buy merchandise. It is easy to remember! I think to an end user it could be XXXX. Honestly it is a very solid name. I don't understand though how dot club will affect the pricing. I think a domainer would give XX to XXX tops.
I'd be looking at merchandising companies that were 5 years old and younger as potential end users for another website to sell!!
