Read this story by Jose Romero at SeattleTimes.com and you read the following;

Interesting tidbit of the day: Hanauer said he has his full crew of staff and coaches at the combine, and that includes the person the club is looking to hire as the final member of the coaching staff. Hanauer wouldn't say who that person is, only that he is "kind of a free agent."

Read this recap at Goal.com and you read the following;

Ezra Hendrickson was spotted around the stadium wearing a Seattle Sounders FC top. Seattle is rumored to be in the market for one more assistant coach and E-Z wouldn't be a bad choice to fill that role.

Who is Ezra?
CONCACAF national who chose MLS (123 caps with his national team)
Former US College player at Drake
Played in USISL, MLS, USL and again MLS (15 year pro)
Played with Sigi in two different organizations and has experience with five different MLS clubs

I don't know if anyone is better than Ezra for the 2nd Assistant role, but he seems a great fit for what this league can grow to be.
