Your apparently punting FG% so I would be patient with Rubio because he seems perfect for what your attempting to do and what he can provide.
With regards to the other players, I feel its a toss up. There's got to be better options in a ten team unless you league aggressively attacks the waiver.
There aren't really any other better waiver options besides a bunch of injured players who I'm just keeping a watch on. I'm not in a good position for playoffs yet so I can't stash Granger or Rose even if I'd like to. My league is very competitive so players are always coming on and off waivers..
