Obviously not a popular option but I have great respect for the Canterbury Club.
What really brought it home to me was being at the Lang Park double header last year when both Brisbane and Canterbury acted as hosts. When Canterbury took over during the second game you could just feel the embracing nature of the club with their presentation for one of the fans and various other things they did. Really put the Broncos to shame (not that I support them).
My missus (who is from a non-football, Victorian background) noticed this also and made a comment on the difference.
Another reason is I enjoy their derby games v Parra, Souths, Saints and Wests Tigers.
