The Houston Dynamo have sent midfielder Andrew Driver and a 2016 draft pick to DC for goalkeeper Joe Willis and defender Samuel Inkoom.
Willis was a backup keeper in DC but has experience, filling in when Bill Hamid was injured. Inkoom, a right back, could back up Kofi Sarkodie in Houston or move into the midfield.
Driver came to Houston from Scotland and can play wide or in the center of midfield.
