The NFL is redoubling its efforts to reinforce the league’s gambling policy to players in the wake of a rash of recent violations.

All rookies will now be required to attend mandatory education sessions, and a group of league officials is making in-person visits to team facilities to emphasize and clarify what activities are prohibited amid the rapid proliferation of sports gambling.

The six “key rules” of the gambling policy that the league officials will emphasize are:

  1. Don’t bet on the NFL;
  2. Don’t gamble at your team facility, while traveling for a road game or staying at a team hotel;
  3. Don’t have someone bet for you;
  4. Don’t share team “inside information”;
  5. Don’t enter a sportsbook during the NFL playing season;
  6. Don’t play daily fantasy football.

The mere decision to schedule the session with reporters is itself noteworthy and can be seen as a reaction to recent events. Five NFL players were suspended in decisions handed down in April.

And this month, an investigation focused on Indianapolis Colts cornerback Isaiah Rodgers came to light, with sources telling ESPN that Rodgers is believed to have placed bets on Colts games. Miller, citing the ongoing investigation, declined to comment on the status of the Rodgers probe.

The league is also focused on intensifying its monitoring and policy enforcement efforts with the help of external monitoring firms and the various sportsbooks. The NFL is hopeful this will create additional deterrence.
