Brock can always win because he's such a good grappler and so strong and when he locks in an arm choke like that forget it. But he did not like the stand up and if Carwin paces himself he's strong enough to maybe nullify Brock's wrestling. Brock will be all takedowns from now on against good punchers. He did not like that standing. On the one hand credit to him cause he fought through adversity and showed heart but on the other hand if there was a sense of invincibility about Brock its gone now.
