I think a real, live tiger at Melbourne zoo should be ordained the Official Living Embodiment of the holy Richmond spirit. The kiddies would go nuts - all kids love animals! It would be somewhere to take budding Richmond supporters and thoroughly indoctrinate them while they are young. "Look, there's Jack, the real Richmond tiger! Isn't he beautiful!" What other teams could offer such an opportunity? You can't visit/see/identify with a "power", a "docker", a "blue", a "bomber" or a "demon". It wouldn't work with a "saint". Almost all the other clubs that have animal mascots, do not have animals that would be particularly interesting to a kid - who wants to see a "magpie/hawk/swan/crow/eagle"? There's nothing special about a "cat" or a "dog". Brisbane, and maybe North, are about the only other teams that could do it.
And when the Holy Tiger passes away, there could be a dalai lama-esque passing on to a new young cub in the zoo, who would fulfill the role for the remainder of his/her life.
Be even more feelgood if some corporate support could be rustled up to help in the animal's upkeep - I'm sure the zoo is interested in any kind of sponsorship they can get.
Sounds rather off-the-wall, but if you think about it, we do have an advantage over other clubs in that we could 'exploit' our mascot/nickname in a concrete way that almost all the others can't.
