Euro soccer and the promotion/relegation system sounds interesting at first, but if you go back it seems like the same clubs flip flopping every season. So, your club moves up from Series B to Serie A. They have about as much a chance of progressing into the upper half of the top division as I have owning an NFL team. Teams move up, get curb stomped, hang around the bottom 4 or 5, and get relegated again. Manager fired, another rebuild starts. Wash, rinse, repeat. See also: Premier League.
Does anybody want to see NIU promoted to the B10, and Indiana drop to the MAC? Then switch back next year? Does B10 wants to see Rutgers get relegated, and they lose that major media market?
