As much as I love NFL and NBA they are not the best way in my opinion even though they are great.
I believe the divisions kind of tournment is much more enjoyable, like we have in real football.
DIV 1 - TOP 1 CHAMPION , BOTTOM 2 RELEGATED TO DIV 2
DIV 2 - TOP 2 PROMOTED TO DIV 1 , BOTTOM 2 RELEGATED TO DIV 3
and so on...
Having as many divisions as possible in a structured format would be awesome.
