I was realy surprised at the figure, I suppose id never realy thought about it before.
Say for instance, Us and Brighton went up this year and Jacks, QPR and Norwich come down, and Charlton, Sheffield United and Sheffield Wednesday come up from League 1 with with Peterborough, Doncaster and Bristol City going down.
That would leave only one team, Millwall in the Championship for 2011-2012 who hadnt played in the Premier League.
