I really can't understand the mind-set of someone who wants to buy a random football team unless it was one you supported.
How can you call yourself a Giants fan but then go all out to buy another team you have no connections with from the same city.
I know in America it's different to what we're used to in the UK. Football in the UK is not about the 'franchise' (unless your the MK Dons)! The clubs are very much a community thing and you support them for life however shit the teams are. If your a Birmingham fan and you were a billionaire you wouldn't then go and try and buy Aston Villa as you would never be accepted. (Although it's clear Jon won't be accepted but for different reasons).
He also always used to say when he owned the Soul that he would never by an NFL team because they are already well established and he wouldn't be able to have the influence over it.
It's hard to see what exactly his motivations are for this. Is it just a vanity project?
