The Gamblers also got the attention of a few NFL teams. The run & shoot offense would be adopted as the base set for the Detroit Lions, Atlanta Falcons and the Houston Oilers. All 3 teams were in the upper half of the league in scoring while using the run & shoot. In spite of this fact, the offense was widely discredited as a gimmick in the NFL when none of the 3 teams won a Super Bowl. Even after those teams moved away from the run & shoot as their base sets, the influence of Mouse Davis and Jim Kelly left a lasting impact on the league. In the 1970s most teams ran the 2 back "pro-set" as their base offense with fixed routes. Today, almost all NFL teams incorporate extensive packages of 4 WR sets and option routes for WRs depending on coverages faced, innovations that are the basis of the run & shoot.
