During the 1973 NFL season, the Oilers' offense stunk. They couldn't run the ball (they finished last in rushing with 1388 yards), they couldn't get first downs (they only managed to pick up 193), and they couldn't protect their quarterback Dan Pastorini, who routinely played with broken ribs in the early 1970s (he was the first quarterback to wear a "flak jacket"). And they weren't much better on defense, either, giving up 447 points that season. Those things combined to create a recipe for disaster, which was exactly what the 1973 season was for the Oilers.
