I'm wondering if Melbourne are just treading water trying to minimise the damage on the scoreboard by trying to hold onto the ball. I'm sure once they get someone like Hogan or Clark back to straighten them up, or even Dawes, they'll try to be more direct going forward.
Unfortunately for them, their skill level isn't up to it, so they're always going to be burnt on the turnover, which happens way too frequently for Roos' liking.
