Same thing for me when it comes to the Premiership. I was a Fulham follower since the time that Brian McBride was there, and then over the years they added Dempsey, Eddie Johnson, and Kasey Keller. Unfortunately they don't have any more Americans on the squad, but I still root for them passively to do well. I'm more entrenched in the Italian Serie A because that's what I grew up with, and that's where my favorite teams are (Juventus, Catania).
As for relegation, I often wish that the NCAA's took to that concept! UConn would be in its rightful place at the top, and schools like Wake Forest and Iowa State would be in theirs...
