I'm a Silva fan and I can say that Cung as good as he looked against Shamrock would have a VERY difficult time with Anderson.
Although this topic has been discussed to death, my answer remains the same.
Cung is a great striker thats apparent. But SIlva a few levels ahead of him, IMO. He's more accurate, better with angles, better in the clinch, power is about the same, better with knees and he has a better chin.
If he fought him, Anderson would be smart to take it to the ground and tap him out quick but I think Anderson would want to make a statement, therefore I think he'd probably stand and get the Knockout. Probably in the later rounds
