The list of spinners is pretty short and hilarious and with all the SR weak pokemon stuffed down there I'm wondering how people will try to make them work out. If the strategy dex is right, NU's selection of Rapid Spinners includes among its non-SR weak members Spinda and Eviolite Wartortle, and otherwise has Armaldo, Cryogonal and Delibird. On the other hand Probopass and Bastiodon are kinda crappy but sturdy basically guarantees they'll at least get stealth rock up if that's what you want them to do. Notably, though, most stuff that gets Stealth Rock doesn't have much long term offense potential, especially considering the explosion nerf. Golem probably looks like it has the most potential there. Wartortle will probably end up as the dominant spinner though, since it isn't weak to Stealth Rock and can kill has STAB super effective water attacks to bring down any hazards layers.
NU is going to be an interesting tier though. It's a combination of pokemon with good typings but bad stats, Pokemon with hilariously bad typings but a couple of decent stats, and most of generation one (which I guess was both :\). I'd love if the ridiculous disparities between the defensive and offensive stats in most pokemon cause shit like shuckle to get some use, though i'm guessing that at the end of the day there will be few surprises and most of the top threats will be top threats from past generations without the power creep shit that walls or sweeps them in higher tiers, like Tauros.
