When the Cowboys officially made the decision to move on from Scott Linehan and find a new offensive coordinator, a lot of fans were hopeful that it would be someone from outside the organization that could bring in an offensive system similar to the prolific offenses of the Rams, Chiefs, and Saints.
In the end, the Cowboys stayed in-house and promoted quarterbacks coach Kellen Moore to offensive coordinator, which seems to strongly suggest that Dallas believes it has the correct offensive scheme in place, but they just want a new play-caller to mix in some creativity and unpredictability.
