A calculated risk would be to rest him against teams we have minimal chance of beating. Tomorrow's game springs to mind as does R5 v WCE. I would be going in all guns blazing against the weaker teams because they are our best chances to put wins on the board.
“There tough so we’re not going to try” would have to be one of the worst things I’ve ever heard.
That’s giving up before you even start, if you’ve got that mentality you’re not fit to coach, nor play at AFL level.
As already posted a calculated risk would be to rest him against teams with a single poor ruckman that we should be able to beat any way, even then that underrating your opponent which is not something you should ever do becouse t leads to losing games you shouldn’t.
