I think Melvin hurt him with that head kick and just doesn't realize it.
Guillard is really landing those leg kicks. Forcing Varner to stand more upright instead of his usual crouched stance in order to redistribute his weight from the lead leg to a more central position. This gives Varner less power behind his right hand.
Varner should really start kicking Guillard as well to take away the movement of Guillard.
Varner had him hurt at the end and got the TD how do you give Melvin what up till that point was a close round?
