One thing about having a 'Magazine" style show during the off season, is what real content are you going to have to put in it? Firstly many league journos have a break after the Grand Final, unless there are rep games to cover. Hence many of them are out for a few weeks just recuperating.
At the same time, barring any end of season rep games, most of the players are on holidays until early November which is when most clubs start pre-season training. Much of that training is straight physical work at first, and a number of clubs have started going away on camps and what have you. They don't invite the media to those things.
Then when you get to Christmas, that is when many football club staff take their holidays. So the off field support staff in the marketing and membership areas, which is where the media usually go to as contact points, there is no one there as they are on holidays for 2-3 weeks.
Also, if there were end of season repo games, many of the players involved in them won't resume club training till mid-January or so. As such they aren't available for the media.
Add all that up and it does not surprise me there is no such show to be honest.
