In no particular order....
Sharks. They have nothing. Halves are a waste of space, their pack is made up of hacks and powderpuffs (with the exception of Ben Ross, but one man does not make a pack), and that backline is simply atrocious. Plus they have little or no depth.
Raiders. They have slightly more than the Sharks in that they have guts. And Jason Smith. Which may barely be enough to save them from the cellar. But again, they have nothing up front that looks even mildly impressive, their halves consist of an ageing, injury prone five eighth who'll need a Zimmer frame to get between plays, and either a sub-par hooker or useless young gun at half. The backline looks weaker than a crown from a christmas cracker, with the exception of Schifcofske.
Warriors. Losing points really won't help their cause. Neither will the fact that Clinton Toopi is still on their roster. They have no decent halves unless Fien can find form, a so-so pack and a lacklustre bench. The backline is decent, but with only two forwards giving reliable go forward in Wiki and Price, and no halves to give them ball, and Clinton Toopi inside a decent winger but seemingly unable to pass to him, a good backline is about as useful as, well, Clinton Toopi. I can't see them finding the form or team work they need to avoid the cellar, but out of these three they are most likely to prove me wrong IMO.
