Collazo was doing the majority of the clinching

[blockhead]

he did that so hatton didnt head butt him, and it obviusly didnt work did you see the cut on his head???
thats Hatton going insane with the head, and just swinging it all over the place

ummm, that headbutt came from collazo. his head hit hatton right between the eyes. but in regards to the clinching they both used it as a means to work one another and neutralize. hatton tried to clinch and work inside and collazo clinched to neutralize hattons inside offense. pure and simple clinching is a strategy, and they both used it.
