How will RBs coach Gash affect Lacy?

After piling up 1,435 combined yards and 11 touchdowns in 15 games, Green Bay Packers running back Eddie Lacy earned NFL Offensive Rookie of the Year honors. Since then, his running backs coach Alex Van Pelt was moved to quarterbacks coach and replaced by Sam Gash. You may remember Gash as a long-time NFL fullback, who blocked for the likes of Thurman Thomas, Jamal Lewis, Deuce McAllister and Curtis Martin.
