I viewed it as Austin coming on to be a more defensively able old head.
He certainly wasn't a force in attack.
But I did read he was straight down the tunnel at the end and sidestepping fans on leaving. I'm not trying to start rumours, 2+2=5 far too easily, but maybe he's not fully happy?
It was a sensible substitution, but surely he can put more effort in for the final 10 than he did? I saw Cheltenham Clown Car Kostiuk mention that about Austin going down the tunnel at the end and so dismissed it out of hand. That's a shame if he did as at the final whistle there did seem to be proper celebration between the players for getting the lack of win monkey off the backs. Williams in particular seemed cock-a-hoop. (probably on a large goal bonus/double figure for the season goal bonus
)
