What's the actual ruling on "obstructions"? I know that they changed to something more broad like "impeding an opposition player".
To me it looked like Vaulks (?) didn't move from where he was or make an action to deliberately obstruct Saville (grabbing him etc). But he definitely knew what he was doing if you catch my drift?
Personally from what I saw live and from the highlights it didn't look like a foul to me (unless the rules are clear?).
Edit: Just been looking back at the corner on a loop for tha last few minutes, it does look like Vaulks appears to shadow Saville and slightly blocks his path and leans into him. The more I watch it, the more it looks like he impedes Saville.
