The St. Louis Rams confirm they have agreed in principle to trading the No. 2 pick of the draft to the Washington Redskins for three first-round selections. Chief operating officer Kevin Demoff on Saturday confirmed details of the deal to The Associated Press. The trade cannot be completed until Tuesday. FOXsports.com and ESPN.com first reported details of the agreement Friday night. The Redskins are paying a hefty price to move into position to take Heisman Trophy winner Robert Griffin III. They\'re giving the Rams their first- and second-round selections this year, plus first-round picks in 2013 and 2014. The deal shifts the Redskins up four places from sixth in the April draft, leapfrogging any other team that would have an interest in Griffin, the Baylor quarterback. The Indianapolis Colts are expected to take Andrew Luck with the No. 1 pick.
