Left tackle Marvel Smith, who was hampered by a pinched nerve all last season, is one of four offensive line starters in Pittsburgh returning from injury last season.
Serious injuries to Smith, Alan Faneca, Kendall Simmons, and Jeff Hartings undermined the Steelers’ chances last year. A healthy line this season could mean solid numbers for Tommy Maddox, Hines Ward, Plaxico Burress, Duce Staley, and Jerome Bettis.
