Remembering the Seattle Sounders win over Toronto FC in 2016 to take MLS Cup is fun, but it is poor preparation for MLS Cup 2017. Both teams are changed, in some ways obvious and others that only those who follow the teams intently may notice.
A Toronto win would qualify them as having the greatest season in MLS history, with a treble and the points record. A Seattle win would put them in the lofty company of LA and DCU in winning back-to-back MLS Cups.
SaH: The biggest change for Toronto is the addition of Victor Vazquez.
