Agree. Flannery's loose play made up for the line-out problems.
Its not automatically the hookers fault and O'Connell as signal caller should at least take some of the blame for continuing to call to the tail. When the lineout isn't functioning you throw a few to the front jumper and/or cut the numbers to build a bit of confidence. You don't throw high risk ball to the tail.
Whilst I understand the reasons behind not challenging opposition lineout near the line, I fail to understand not doing it further up the pitch.
