The AFL is eating itself right now.
McLachlan is the quintessential, professional corporate suck and he's not the type to do a runner from a CEO job with someone like the AFL without knowing that some headwinds and subsequent personal brand damage are coming his way. He's getting out now and positioning himself for something else before things turn sour at the AFL.
He'll get a lucrative deal done with the tv/streaming rights, get big pats on the back, then get out before ratings drop consistently for a second and third year, and the acquirers realise they've overpaid and everyone in the sycophantic media starts belatedly saying "The game is in ruins !! Where are the crowds ? Where are the viewers ?? What happened ???"
