The St. Louis Rams have decided to trade the No. 2 pick, league sources said Monday.
According to sources, the Rams already have had trade discussions with the Cleveland Browns (No. 4), Washington Redskins (No. 6) and Miami Dolphins (No. 8), each of whom is scheduled to pick in the top eight in April's draft.
The Rams, who already have quarterback and 2010 top pick Sam Bradford, also have discussed a potential trade with teams outside the top 10, according to a source, but it will be challenging for one to surrender enough compensation to vault to the second overall pick.
Manning was selected by the Chargers with the No. 1 overall pick in 2004 and traded to the New York Giants for two first-round picks, a third-round pick and a fifth-round choice.
St. Louis' second overall choice became the focal point after RG3's sterling effort at the combine in Indianapolis on Sunday cemented Griffin and Luck as the likely top two overall picks on April 26.
While neither Luck nor Griffin decided to throw at the Indianapolis event, Griffin was officially clocked at 4.41 in the 40-yard dash, while Luck came in at 4.67. Luck also put his versatility on display Sunday. His broad jump (10 feet, 4 inches) was two inches short of quarterback Cam Newton 's best in 2011, and Luck's vertical jump (36 inches) was better than Newton's (35). Griffin was better than Luck in the vertical jump (39 inches) but fell short in the broad jump (10 feet).
Among the teams Griffin interviewed with in Indianapolis were Miami, Washington, Minnesota and Kansas City. He said all went well, including his talk with Indianapolis executives trying to decide what to do with Manning and that top pick.
