Anderson knew going into the fight with Sonnen that Sonnen's entire gameplan was to take him down. Sonnen never tried to hide it, he said multiple times in public that he was going to take Anderson down, and I quote:
I’ve got two national championship plaques on my wall that says I can take him down. I’ve got a silver medal from the world championships in 2001 that says he can’t stop me from taking him down. If he’s got an answer to it, God bless him.
Anderson knew his gameplan, and failed to stop it, and got beat on for 23 minutes.
I expect the exact same thing (Sonnen getting takedowns whenever he wants), however, who knows if he'll get subbed, or if he can keep from getting subbed, etc.
All I know is, if Sonnen wants Silva on the ground, Sonnen will get Silva on the ground. What happens from there, who knows.
