Positives: "Explosive back who plays with suddenness. Displays solid vision, runs north-south, and keeps his feet moving up the field. Possesses the speed and agility to turn the corner, shows a burst through the hole, and has the ability to make defenders miss in the open field. Quick-footed, creates yardage, and keeps the play inbounds. Solid receiver who extends his hands to make the reception away from his frame. Recognizes blitzes thrown by the opposition and picks up blocking assignments."

Negatives: Not a strong back who picks up yardage off initial contact and easily brought down by a single defender. Never capitalized on a terrific sophomore season.

Analysis: Grigsby has flashed skill the past two years after being one of the nation?s better ball carriers in 2008. He possesses the football ability to make an NFL roster as a third-down back/rotational ball carrier.

Projection: 5th
