It's because he knows Melbourne are untouchable, or at the very least he is assuming as such, and why wouldn't he?
more likely he knows the rules and knows he has nothing to answer for.
Good to see the storm being the ones to take advantage of the new rules first. They were behind the 8 ball when the HIA was first introduced with Parra being the team to create the 18th minute HIA. Likely now that it was the storm exploiting the new rule that it will be fixed.
