Dolphins get RB Lamar Miller, avoid WR

The Miami Dolphins made the first trade of Day 3 by moving up six spots to No. 97 to get University of Miami tailback Lamar Miller. He was one of the highest-rated players remaining in the fourth round.

When Miami traded up, I immediately thought the Dolphins had their eye on a receiver. This is a big position of need for Miami, which is installing a new West Coast offense under rookie head coach Joe Philbin.

I have nothing against the Miller pick. It was solid value for the fourth round. However, Miami has a 1,000-yard rusher in Reggie Bush and a promising second-round pick in Daniel Thomas from the 2011 draft. I'm not sure adding Miller to the pile was the best tact if he potentially will be third on the depth chart.

This looks like a "best available player" pick for Miami general manager Jeff Ireland. You can't fault teams for doing that at this stage. But Miami needs to address the receiver position at some point in this draft.
