2017 saw Toronto FC break the record for most points in a season (69), Diego Valeri score in nine consecutive matches and the Sounders become the first team to win a match after going down three goals.
But 2018 has the potential to be an equally special year in terms of record-breaking performances, with perhaps the most important MLS record going down in the process.
San Jose Earthquakes forward Chris Wondolowksi needs just 12 goals to pass Landon Donovan for the most goals in MLS history. The 35-year-old has scored at least 12 goals in seven of the last eight seasons, with his total ending at 13 in 2017. He needs just one goal to move past Jeff Cunningham for sole possession of second place all-time.
