I think that none of those three guys has a chance in hell at beating Anderson. Swick would get KTFO or submitted, assuming he could get Anderson to the ground without eating a knee, and Leben isn't smart enough to handle Silva's control striking and BJJ.
As for Franklin, he got handled.
I think that Lindland probably has a better chance than any of these guys. His wrestling is way more evolved and I think he might actually have a chance if he manages to take the fight to the ground, but so does Silva. But I don't Lindland will come back to the UFC, I think he's under contract with the IFL.
