The phrase "player your club can least afford to lose" can be interpreted in many different ways. It doesn't mean best player or most influential all the time.
There are multiple factors why a team couldn't afford to lose a certain player, such as depth in their position, how much they influence the game plan or whether they could fill the void more easily than others.
Have a look below at my list of who would be the player for each club that they would least afford to lose.
Geelong
Jeremy Cameron has consistently been a top-ten influential player in the AFL since arriving at Geelong, and that hasn't changed at all this year. His goal-scoring ability is unmatched, along with his ability to impact the play anywhere on the ground.
You could argue they would miss Bailey Smith more, but I think they have enough players to fill some of his impact than they do for Jeremy Cameron.
