That's not true though.Always been a fringe player. He plays when we're undermanned. When you're undermanned you lose more games.
Last year he played when our whole list was healthy. He was selected in 21 of our 22 games. Round one he played this year when our whole midfield and forward line (which he plays) was fit bar Graham and Kmac. All players play in teams that have one or two injuries, that's not specific to Aarts.
And even if he's replacing an injured player in a team with one or two injuries, If we're worse when he replaces an injured player, maybe we should be trying someone else to replace an injured player?
As I said, win/loss isn't everything, there are lots of other reasons why Aarts is not a good selection. But even if he's our break glass in case of emergency (which he hasn't been), what's the point of breaking the glass in a fire, and finding a bunch of accelerant instead of an extinguisher?
