You were joking when you described basketball as a minority sport... maybe... but I felt bad when I said Mavs were a smaller version of United... so I looked it up and then I didn't feel so bad. I didn't realise how niche US sports are, I think, correct me if I'm wrong the biggest team (franchise) in the US across all sports is Dallas Cowboys.... and if you look up their total support it's about the same as I dunno Wolverhampton Wanderers or Ipswich Town or something. In terms of people worldwide who care about their games Tottenham are about the size of the entire NFL.
