I listened to that interview and didn't hear that at all - thought it was the opposite. He's said over and over that Hinkley is contracted until next year.
The way I interpreted it was Hayes asked Richo a loaded question. Something like "Surely Kenny has done enough to be coaching in 2023?" Richo then mentioned how he's contracted for 2023. Cooney then asked something along the lines of whether we'd need to play finals. Richo then mentioned it being a performance industry but there's no point speculating. Basically saying we'll take it 1 week at a time. Maybe I was just in a good mood when I heard it but I interpreted it as Hinkley being gone end of year
