Todd McShay has come out with his latest Mock over at ESPN, and it doesn't offer a lot of surprises. Since he does not project trades, McShay has the Redskins staying at No. 6, but he also has Oklahoma State wide receiver falling to that spot. Here is his rationale.
This pick is made with the assumption the Redskins do not trade up to take Griffin and plan to fill their quarterback need via free agency (Peyton Manning?). They also have a need at cornerback and would likely take Claiborne if he were available, but in this scenario Blackmon is the best choice. He offers an upgrade over current starters Santana Moss and Jabar Gaffney and would give Washington a big-bodied receiver who can produce down the field.
Most of the mocks we've seen have Blackmon going somewhere in the first five picks and therefor unavailable to the Redskins. But if he does last to the Redskins and some of their other targets are off the board, Blackmon would be a good fit for a Redskins team that is pretty thin on true playmaking receivers.
