Dolphins trade out of 12th spot

ORCHARD PARK, N.Y. -- While Buffalo Bills general manager Buddy Nix and vice president of college scouting Tom Modrak were explaining why they chose Clemson running back C.J. Spiller with the ninth overall draft pick, the Miami Dolphins made a trade.

The Dolphins dealt their 12th pick to the San Diego Chargers for the 28th and 40th selections in the draft.

The Spiller selection likely played a role in the Chargers' decision to move up.

In need of a running back to take over for LaDainian Tomlinson, the Chargers selected Fresno State's Ryan Mathews.
