I'd rather see Davis either stay at the 4 or get bigger and move to center rather than take over SF. I understand the need at SF and how important it is to have someone who can defend Durant or LeBron, but I don't think Davis could ever be comfortable there.
Same for Anderson. His game fits him playing the 3, but he's too slow footed and he'll be a defensive liablity(which hurts even more since Vasquez is already a liability at PG).
I'd like for a situation where Anderson and Davis could be in the lineup together, but I don't think SF is it....at least not permanently. A bigger lineup of Lopez-Davis-Anderson-Aminu-Vasquez would be nice every once in a while. But the best bet is to draft a guy like Otto Porter or Shabazz Muhammad. Let Davis get stronger so he can play center and then move Anderson into the lineup.
I appreciate the question though.
