The Rams have agreed in principle to send the second overall pick to the Redskins for three first-round draft picks and a second-round pick, according to a source familiar with the deal. The trade cannot be signed off on until the new league year begins on Tuesday. In the deal, St. Louis will receive Washington's sixth overall pick, as well as the team's first-rounders in 2013 and 2014. They will also receive Washington's second-round pick this year. The Redskins will draft whichever quarterback the Colts do not, likely meaning Robert Griffin III will land in Washington.
