I disagree. I think their is basis that Beale is the most likely replacement for Cooper should Cooper be injured, but I just don't ever see him being a contender for the number one spot. He's only fighting it out for second choice.
Let's just remember that up until less than a year ago, probably half the rugby public in Australia didn't think Cooper was up to it against the top teams.
Having lots of players in form can only be a good thing for Australian rugby.
The fact that the two major changes in this side was for two guys in outstanding form (Beale and AAC (Adam Ashley-Cooper)) to oust players who also are in very good form is something I don't think we've seen in the Wallabies for quite a while.
In previous years it's been a case of players in pretty dire form struggling to lose their spots because the other options whilst playing well weren't pushing strongly enough to take their spot.
Look at Horwill for example. He's in much better form now than when he couldn't lose his spot last year (albeit he only just kept it due to an injury). Benn Robinson still can't make the squad and is playing much better than he was a year ago. Signs are good.
