Kellen Moore was 53-0 as a college QB. As a pro with two teams (DET, DAL) he played in parts of two 2015 season-ending losing games. Nothing about his record-setting college career suggests his meaningless NFL playing career directly relates to success as an OC in the NFL.
KM, without any previous coaching experience at any level, was given the 2018 QB coach job, where he oversaw a group of 3 players.
Now that he has — once again — been GIVEN the OC job for DC, there is no proven indication that he will succeed.
It’s puzzling that so many self-proclaimed knowledgeable fans are banking on him to be the overriding difference in the Cowboys’ 2019 fortunes — one way or the other.
