Transfers 

For transfers in, dates listed are when Sounders FC officially signed the players to the roster. Transactions where only the rights to the players are acquired are not listed. For transfers out, dates listed are when Sounders FC officially removed the players from its roster, not when they signed with another club. If a player later signed with another club, his new club will be noted, but the date listed here remains the one when he was officially removed from Sounders FC roster.

Draft picks 

Draft picks are not automatically signed to the team roster. Only those who are signed to a contract will be listed as transfers in. Only trades involving draft picks and executed after the start of 2017 MLS SuperDraft will be listed in the notes.
