Step was an undersized technician. Fred has the size, physicality, and technique. He’s the complete package. I would take the current O-line over the 92/93 unit.
On a player by player comparison, yes; however, as a unit the 1992/1993 OLines were dominant.
Also the current unit lacks the Erik Williams fear factor. IMO EW in 92/93 (pre car wreck) was the most dominant and feared OL in NFL history. He was the best player at his position on those teams. None of Emmitt, Aikman, Irvin or Haley were consensus #1 rated at their position but most people including John Madden rated EW as the best.
EW had 3 Pro Bowl and 2 All-Pro selections AFTER the car wreck but he was never remotely close to the same player.
Many Cowboys fans think Larry Allen was the most feared but LA just bullied people because it was fun. EW was an angry player that literally wanted to kill the opponent.
