Gabe Jackson represents a changing of the guard for the Raiders in ways that go beyond inserting the rookie third-round draft pick into the starting lineup.

With general manager Reggie McKenzie on record as saying, "We want to do the pushing around. You do that with big people," Jackson is a mover and a shaker at 6-foot-3, 336 pounds.

In past years, as the Raiders have gone back and forth from zone blocking to gap and power blocking, the guards, including departed players Cooper Carlisle and Mike Brisiel, were more suited for attack from the side rather than head on.

Other starting guards in recent years, such as Robert Gallery, a former tackle, had started at another position or, such as current center Stefen Wisniewski, a guard as a rookie, were on their way to different position.

With the Raiders wavering on what they wanted from their guards, perhaps it's not surprising they haven't sent one to the Pro Bowl since Steve Wisniewski in 2000.

Jackson, if all goes according to plan, will give the Raiders a pure power road grader. He's built like a kitchen appliance, and his forte is forward progress.

A four-year starter at Mississippi State, Jackson made 52 Southeastern Conference starts and seldom took a backward step.
