I absolutely count the ones from Minneapolis. That's where the franchise was at the time. I think if it was any other franchise than the Lakers we wouldn't even think about it. They were bitter rivals when they were in Minnesota too.
The ones that bug me more are things like the Baltimore Ravens winning a championship after they moved from Cleveland. That team had old Browns players on it from the move, yet the lineage of the Ravens franchise supposedly restarted when it moved to Baltimore.
Look at it like a family tree.
