Not sure if this was mentioned up-thread, but it appears Moss was required by league rules to do this media availability.
http://www.profootballwriters.org/nfl-media-access-policy/
Assistant Head Coaches & Primary Position Coaches – Permission to interview assistant coaches about reasonable football issues throughout the year should not be denied.
Regular and reasonable access to assistant coaches – coordinators/assistant head coaches and all primary position coaches – will include at least one mandatory media availability during the club’s offseason program and at least one media availability per month beginning in August through the conclusion of the regular season for media that regularly cover the team (offensive and defensive coordinators will continue with their weekly in-season media availabilities as described above). The structure of these sessions is a club decision (i.e. availability on a single day or multiple days, press conference format or on the field following practice, etc.) but all assistant coaches must be available during each of these three time periods.
Please note that while all assistant coaches must be available at least once during the offseason program and once per month beginning in August, it is not permissible to deny all other requests because of these mandatory availabilities.
Access to assistant coaches on game day is a club decision, and any game day access to assistant coaches would be in addition to the mandatory access rules described above.
