The Cowboys offensive coaching staff still hasn't been officially announced for the 2019 season. The contours of what the group will look like are known, but the exact responsibility each coach will have has yet to be determined. At least to the outside world. Internally, the Cowboys brain-trust likely has a pretty good idea of what is going to happen.
In general, it’s thought that Kellen Moore will take over as the offensive coordinator, Jon Kitna will take over Moore’s old job as quarterbacks coach, and tight ends coach Doug Nussmeier will be involved in some way with the offensive game-planning.
