Mm a bit of an assumption that really, the motivation of those that buy football clubs are many and varied. Mel presumably saw a chance to be a local hero and get the club into the pre. Clowes going by what he said, bought it because he couldn't bear to see the club he supports go into liquidation, Those that bought Newcastle are looking to use it as a way of improving their reputation and influence. Others go into it to make money (Mike Ashley) others yes want the glory and I guess others just want to own a local piece of the community and its history and are under no illusion that they will either get any glory or take the club beyond where it is now.
Yes they all would like to progress, but most have a limit on what they can spend to achieve that and most probably never will.
