@Klaous - I'm not saying historically they have been a better league. Greek teams have more skins on the wall in Europe.
But, yeah, the crippling economy is exactly the reason they are a better league right now, especially at the top, where other than OSFP I don't think a single Greek team would crack their top 5 or 6 in terms of wage budgets. The last several years, by September, 3/5 Greek teams are already out of the competition. I think we've only had two teams get to the group stage each of the last 2 (or 3?) seasons.
But you are probably right, I am willing to drop the second "much" in my prior statement. They're just a "much better league" right now, top to bottom.
