His problem is his disposal.
Only more expericence will fix that.
He is a really good 3rd man up and when Yarran finally plays hopefully playing Batch means Vlaustin can stay in the guts
How much more experience does he need. His already played 79 games and if anything his ability to provide a rebounding option and use the ball efficiently has got worse each season since his second. Which although he has played a different role since then that doesn't change the fact that more should be expected out of him with regard to providing rebound.
Come the end of the season we should be looking to rebuild the backline before any other area of the ground. Chaplin, Batchelor, Hunt and Morris shouldn't be anywhere near it come round 1 next season.
