Why not make the play-offs go all the way down from 3rd to 24th, eliminator style, until the final is the winner of the entire EFL playoff pool versus the third worst team in the Premier League.
Just think of the mayhem when a team that should’ve been relegated to League One manages to beat a Premier League club and gets promoted instead. Oh yeah, and it’s basically a straight position swap - so if the PL side lost to a relegated Championship side, they’ll end up in League One.
Nothing quite like the threat of double relegation to make it more interesting.
