Do we blame the guy getting games or the guy giving the games to him?
Option C, we blame:
For a few reasons.
1) He is choosing to leave.
2) His form clearly wasn't good enough to force anybody else out of the side. And apparently it wasn't even good enough for him to be given opportunities before Swift or Dalziell. If he'd been consistently good in the WAFL all year he would have been given more opportunities at AFL level.
Thirdly is more of my personal opinion and a reason I'm not terribly upset about losing him. I realise he was reasonably young but when he did play at AFL level he didn't do anything spectacular. He did a lot of okay things that basically any fringe player could do. Guys like Swift and Masten are prone to do terrible, horrifically ugly things on occasion which sticks in people's minds (Masten less so this year). But they also do a handful of outstanding things when they play that go unnoticed by 95% of West Coast fans who like to focus on the bad things. Koby didn't screw anything up too badly, but he never looked like doing anything amazing at AFL level either.
Time will tell, but I don't think it's fair to blame Woosha or Swift for this, Koby is rolling the dice and looking for opportunity elsewhere so that's who I blame. But I don't have any ill-will either, I hope he flourishes in the VFL.
