The 10-time Pro Bowler has left a pile of frustrated linebackers and flattened defensive ends in his wake. Roaf brings 6'5" and 320 pounds of road-grader power to the Chiefs' left tackle position, clearing the path for Priest Holmes, Larry Johnson and anyone else lucky enough to run behind him. Kansas City's offense has ranked at or near the league's best since 2002, when Roaf arrived to cement down the most vital position on the offensive line. Roaf isn't allowed at autograph signings for Holmes or Trent Green, since he never lets anyone get close to them.
