We certainly are not their bogey side, I believe the Warriors have that to their credit, as their hot potato style is the direct antithesis of the Storm's, and thus they refuse to engage them on their terms.
I think the statistic you quoted us right, as we were 1 from 11 prior to round 25? If not exactly correct, it's indicative of recent history.
Despite not being the bogey side as it were, we are showing over the last two years we can be competitive against them. The biggest knock on us from 2011-2014 is that we rarely earnt the respect of top tier teams, and our results bore that out.
Since last year though, we've gone 2 from versus the Storm, and I think we have earnt back the respect in the process, as well as garnered the self confidence necessary to earn those wins.
Despite that, I fear the Storm more than any other team. No one else is better at imposing their will on the contest and exploiting your deficiencies, while pushing you to play away from your strengths.
