Although Davis has great wrestling, his MMA wrestling is still not that good. He had trouble taking down Gustaffsson and Lil Nog early on in those fights. But he has got some good BJJ. Nobody has been able to take him down outside of Rashad and I dont see Vinny being able to. Davis does have the advantage in the standup, and I dont mean in terms of striking, I mean standup. He is more athletic on the feet, his movement will be too good for Vinny (subpar striker) to catch him with. Davis can also freely kick at Vinny, and not worry about being taken down, as he can prob get back to his feet.
I think Davis outstrikes him, and mixes in some Td here and there, and cruises to a UD.
