FRISCO -- When Zack Martin's contract extension is eventually finalized, the Cowboys are expected to have their three All-Pro offensive linemen (Tyron Smith and Travis Frederick) signed through the 2023 season.
The unit is regarded as Dallas' best offensive line since the great groups they had in the early 1990s, some of the best the game has ever seen.
There are some other similarities to those teams that won three Super Bowls in four years. With Hall of Fame running back Emmitt Smith leading the way, those teams were also built around the running game.
Several of the key players during that time were also relatively young.
