Souffs season-long injury crisis is a myth. If you actually go back and look at your team lists, you've kept a very consistent 17 up until the last month or so (and your form wasn't any better than it is at the moment). You've had two players missing long term - Ben Ross and Michael Crocker.
Saints have had a very similar run. A remarkably consistent 17, especially in the backs, with a couple of long-term injuries in the forwards and on the bench (namely, Dan Hunt, Nathan Fein, and Jeremy Smith). To put some numbers on it, I've done up a list of each side's top 17 (feel free to quibble my selections) with the number of games they've missed. Interestingly, Souths and Saints both have 5 player who haven't missed a game through injury (Wesser, Talanoa, Merritt, Sandow, Burgess; Boyd, Morris, Gasnier, Soward, Creagh), which is about as good as you could ever hope for.
Quite simply, if Souffs were as good as their pre-season hype, they'd be in the top 4 currently, and wouldn't be relying on a miracle to sneak into the 8. Where you sit currently on the table ahs nothing to do with injury and everything to do with your own ineptness.

p.s. To clarify my earlier comment, it is extremely rare for any team to be able to name what might be regarded as their first choice 17 (assuming such a thing can be defined). When I said "full complement" I was excluding Ben Ross, and noting the fact that Souths had a very consistent side up until they got hit by injury in the last month (might have had 1 or 2 out any given week, but not half the bloody team like they currently have).
