Nah, not really. More a few teams that I refuse to support, such as St Helens and Wigan. You know, the overachieving ones.
I guess I'd go with Les Catalans because they're French and they have Stacey Jones in the side. I just never get much of a chance to watch many (any) games, but I did catch the last 20 minutes of a Challenge Cup game, with Hull KR (the National League side - like reserve grade, I guess) trouncing Warrington. I like it when that sort of thing happens.
