I thought he had a pretty good game but yes this was a bad turnover in terms of timing as he had multiple players free, which if hit could have taken the ball inside 50 and perhaps we might have got a goal. My mate, a demon fan, said to me - as soon as Morton hesitated - "he's gonna stuff this up" and sure enough he did.
But a bit of perspective. Both Watts and Trengove each turned the ball over with a poor kick and a direct goal and on both occasions each player elected to kick left footers (when they could have used their natural foot).
