Tito Ortiz in his earlier years in the UFC would just ground and pound the whole time instead of going into a submission. You have to take in acct that Brock is still learning the UFC "ropes" and that submitting is out of his comfort level. If he doesn't learn any BJJ submissions/defense he'll have a hard time against the top tier heavies in UFC. But I definitely agree that Brock had Herring's back numerous times and did not go for the rear naked choke. Then again he could have been trying to put on a show for his home crowd and was going for the KO. His lack of class needs to go, riding a horse and then roping it as well as pointing at Herring b/w the 2nd and 3rd round will get him a good beat down by a much more established fighter.
