While even Cerrone was disappointed with his inability to finish, I think the leg kicks and Rochas reaction to them was a visible finish regardless.
Its clear that if Rocha had to continue the fight any longer, he couldnt have sustained many more leg kicks.
I think Cerrone was just hoping he could finish him with the leg kicks, but Rocha was tough and kept throwing some wild punches that were at least catching Cerrone just enough to make him a bit more timid than we'd all have liked to see.
Its too bad the striking was so one sided that we didnt get to see more of a ground battle, as I think Cerrones skills on the mat are worthy of note and I think fans of the UFC that didnt watch much WEC havent seen yet.
Cerrone probably has to get better at his wrestling still, especially if he doesnt want to suffer a similar fate as Miguel Torres, in being a great exciting striker/submission artist but complacent in takedown defense costing him decision loses.
If he can become offensive with his takedowns more like GSP, I think he can really be a devastating fighter because of his great standup, great submission game giving him the ability to win fights in both realms.
I hope to see him one day fight for the UFC belt, simply because I think if you put a guy who will stand and trade with him, he'll oblige and make some VERY exciting fights for the fans... he's that type of fighter.
