Bonnar landed those shots because Silva let him. Anderson's speed advantage on JDS would be ridiculous and he has the ability to take any man out with any strike.
Why is there no doubt? What is there to show that a 240lb Dos Santos has anything on a 220lb Anderson? Who's to say that JDS can even land anything significant on Anderson? Yeah, JDS is fast but he's not as quick as Vitor and we all know how that one went. Watch JDS sparring with Shogun, I know it was a few years back and he's obviously improved but as a striker, he's just not on Anderson's level.
Their reach is pretty much equal, Junior is taller and stronger but Anderson is faster and a better technical fighter.
So basically IMO, if JDS doesn't shoot a double then he's in trouble.
Hold on, i probably should have said IMO. As in my mind, he would wreck them all.
