Watching on the idiot box, when Sydney went to a tight one-on-one defense, we were caught out trying to break out of the defensive 50. Our defenders looked uncertain of what to do when there wasn't a player free. They looked like they wanted to wait, and wait, and wait until someone worked free, but due to Sydney's tactics, it just wasn't happening and we coughed up a few turnovers.
When Sydney went back to a zone, we didn't have much trouble working through it.
I think we might see other teams try the one-on-one defense on us.
