If Brown doesn't come back, we'll get another suitable candidate. Some of the doom and gloom on this thread is completely unnecessary!
We're one of the biggest jobs in world rugby, and, unlike the current dearth of player talent, there are still plenty of more than qualified coaches available.
Let's be clear I've always thought, and still do, that Nathan Brown is the shot in the arm Saints need. But that's not to say it will be the end of the world if he decides to stay in Australia. We've got a good squad and life will go on regardless.
