With the transfer window closed there are only a handful of ways that Seattle Sounders can add talent until July 10. They can sign a player who was not under contract as of May 1 at 8:59 p.m. Pacific; they can sign a Homegrown Player; they can sign someone from other American soccer divisions, including from S2.
Down in S2 there is some young talent that might be able to help out. They will not save a season. They can help weather the storm as President of Soccer Garth Lagerwey looks for his DP and secondary signing in July or August.
