Barrett interviewed Adrian Anderson tonight and after a meeting with the clubs, the AFL is seriously considering introducing a mid-season trade period as early as next year. Cameron Schwab pushed the idea and was supported by the other clubs' officials present at the meeting. Basically you would be able to swap players plus trade off/for future draft picks. So you could have the scenario of a player playing for their existing club up to round 11 and then for another club in round 12 and beyond.
Barrett also asked if priority picks will be scrapped. Anderson replied they will be reviewed at the end of the season.
Edit: forgot to add it was mentioned that there's a player push for the return of State of Origin.
