Interesting. MLS Wants to revamp the playoffs. # of games would go from 13 up to possibly 30.
MLS considering significant overhaul of playoff format: Sources - The Athletic
Two options mentioned in the article are:
A) A playoff group stage (Break down 16 playoff qualifiers into four groups of four (keeping within conferences, so there would be two western conference groups, and two eastern conference groups, play each other once (the two higher seed teams in each group would get two home playoff games, the two lower seeds only get one) top two from each playoff group qualify for quarterfinals, then single legged knock out from there
and
B) Two-legged matches (home and away) throughout the playoffs.
My thought: If they're going with option A, make it so all post season games are at the higher seed throughout the group stage (so the top team in each playoff group would get all three games at home, 2nd seed would get two games at home (the third at the top seed on the road), so on and so forth.
