The sad thing is, I just don't know what you can realistically expect from Sanders. I'm a big advocate of bringing him eventually. Because I think the upside and vacant hole at the position going forward needs addressed.
But what does he do for this year? Not much, if anything IMHO. Not playing for years, knowing he won't be in NBA shape, and likely won't be able to contribute that much is still a likely scenario.
But, I don't really know what the Cavs should do. Maybe take a flier on Landy? (I know, nothing real exciting)...
Unfortunately the Bogut injury really fucked us. We are pretty much likely stuck with the Frye, TT, and Love frontline. Yes, they'll probably sign someone, I just doubt that person will have much impact.
