Sponsorship 101: (1)
1 Most SANFL club sponsors do it for part commercial reasons and to raise their profile, but also
2 Out of a wish to be involved, or
3 Because they know someone at the club, or
4 They've been persuaded by someone at the club to be a benefactor, or
5 All of the above.
Sponsorship 101 (2)
It may surprise you, but it costs a shitload more money to get the same exposure sponsoring an AFL club.
West Adelaide FC sponsorship:
As it happens, I've already spoken to our sponsors. West are very fortunate to have great sponsors who love the club and they have all renewed their sponsorship again. The nature of some of their businesses is that they wouldn't necessarily get a lot of commercial gain from their sponsorship, so they do it for all the right reasons and are very generous. I have no doubt at all that Adelaide Galvanising, Broadspectrum and City Mazda are all very happy with their current sponsorship and any extra exposure they may get is welcome.
Your argument is a non-sequitur anyway, but the above makes it even less relevant.
