Ok, so the Rebels have won comfortably and with a bonus point for the first three games. You don't do that unless you have a half-decent team.
Given they have put the Reds, Sunwolves and Brumbies to the sword, you (and I) would probably expect the boys to keep merrily rolling on.
Having said that, we need to remember that this team is still in it's infancy, and trip-ups are going to happen. I have a feeling that this game is going to be one of those. Call it a banana-skin if you like, but the Rebels are not experienced in being winners week in and week out, and that takes a certain mind-set and belief; an arrogance, even. The Reds in particular had it in their championship year; we aren't there yet.
I'm not 100% convinced that we have that embedded belief given our recent history. That will come in time, of course, but right now I think we are still in the "OMG, I can't believe we are winning!" phase. In that phase, it is occasionally a self-fulfilling prophecy.
It is difficult to measure the Rebels place in the Super Rugby standings simply by form, otherwise why would anyone pick against them? Fair call, but I need to see a bit more before I can claim the Rebels are the real deal. Maybe I am being harsh; after all, the boys cannot do better than they have done so far, but I'm cautious enough to keep the handbrake on expectation for the short term.
Win against the Tah's, and of course that gives us the right to claim a clean sweep of the Oz conference. But we all know that regardless of what happens on Sunday, no-one in the rugby world is going to consider any Oz team the real deal until we face off against the Kiwi's and place a few W's against the ledger.
