How stupid are you to have a bet on the team you coach, particularly after players have recently been fined/suspended? It's quite astounding.
As an aside, from next year the MCG won't have any odds on the scoreboard. They're taking some principled stand.
I don't think the two approaches are logically inconsistent. The AFL is saying to people not working in the involved organisations 'sure, have a bet', but saying to people in the industry 'it's not on for you'. How is that a confused message? You're at best an idiot for betting on footy when you're a player/Coach, and at worst you're delberately taking advantage of privileged information.
