You could easily flip that on its head and ask how often, over the last several seasons, have the broncos gone into a game as strong favourites off a couple of good wins, and turned up with a great attitude and performance ?
Even when we were a functional NRL team under Wayne Bennett, the Broncos have developed a habit of only producing big performances off the back of an ass kicking the week before. I don't know how or why, but over the last few years our players just seem to drink their own kool aid far too easily and quickly.
