If I look at Richard Mille, I couldn't tell you which team(s) they sponsored. A good sponsorship tie-up I guess is one where you feel the brands naturally fit together, whether that's customer base, shared values, history together, or there's some other match or depth to their support (for instance, providing timing). And yes, I repeat again, it's all cynical, but surely the idea is to create the illusion of partnership and support.
