You've intrigued me to go and review the incident that got him sidelined...That's the point. Collins wanted him to take the offer, Grant ended up (famously, with the 20c letter) turning it down. A year later Grant is one of the bookies favourites for the medal, (and despite what anyone says to the contrary upper figures in the AFL do know roughly where the tally is at all year) and Collins personally intervenes to have Grant reported and directs a guilty verdict and ban, despite all match officials dismissing the incident as not reportable both on the ground, and after viewing post game replays.
It was a very blunt and clumsy fit up job, well short of the Demetriou finesse to which we've grown accustomed.
