Good post - I totally agree on the unpredictability of leagues making them fun. I've just moved to the US and am loving the sports here. We never know who is going to win NFL matchups each week (and almost every game is close!), baseball playoffs are now between the 'powerhouses' Detroit and St. Louis/San Francisco. It's great. That's what the prem should be.
I'm obviously biased with regards to Manchester United, as I grew up following them, but I'm not sure they've ever 'done a La Liga' and taken more than their fair share of TV revenue. I actually believe the premier league has a pretty good allocation of TV money - though I'd like to see it made progressive (bottom teams get the most). All United did was whore itself out to the rest of the world and brought home the commercial bacon, so to speak. Liverpool really should have done this better - they had the history, the glamour and the name - but didn't manage it.
For me as a fan of the sport, however, I'd gladly give up 10 of our titles to have a balanced, unpredictable premier league.
It'll be interseting with regards to the russian leagues. It's a harder product to sell to the world and players, so thatll be challenging. I think it's more likely the uber-rich will keep buying up clubs in popular leagues, and distorting them that way, rather than trying to move teams to their own backyards.
I just wish I could get hte Championship on tv over here - that's always an amazing league.
