If Vancouver beats LAFC this weekend, RSL beats Colorado (likely), and Houston beats Portland (likely), then the first round of the playoffs will have LAFC playing Vancouver in a best of 3. That would be minimum of 3 games in a row between the two teams and a possibility for a 4th game.

I kind of hate it.

I didn't check Eastern Conference, but there is also a very very low likelihood of Houston and Portland playing 3-4 games in a row. That requires Seattle, Dallas, and San Jose all losing, LAFC losing, and Houston beating Portland by enough goals.
