It's interesting looking at the records of the sides from this point:
Sharks: 8 times in finals, 4 times in final, 0 wins
Saders: 15 times in finals, 10 times in final, 7 wins
Tahs: 6 times in finals, 2 times in final, 0 wins
Brumbies: 7 times in finals, 6 times in final, 2 wins
From a likely choke standpoint, Tahs and Sharks are gone for all money and we'll have the most common final in super rugby history - Saders v Brumbies. But that's only one angle. I'm still leaning towards Tahs v Saders, probably with the same outcome we've become accustomed to.
