The key storyline in this match is not Sigi Schmid versus Brian Schmetzer. It is not the rivalry between the LA Galaxy and Seattle Sounders. It is not even first place in the West being again within reach.
The key storyline will be the starting lineup. Does Joevin Jones start? Which of the internationals need to rest rather than play? Can Jordan Morris break his scoring slump and/or be an effective lone forward.
Those other things are important. First place is there to be re-taken. Sigi v Schmetz is a fun contest.
