According to an Football article
"Many of those coaches have assistants called the "Quality Control Coach." However, the QCC doesn't really do much coaching at all. They spend all day multitasking, breaking down film up to five weeks in advance and analyzing data. They work all hours, in hotel lobbies, on airplanes and at their team's headquarters producing reports for their Head Coach."
Basically the video/matchup weakness scouting guy, which was what Owens was anyways
