If Ortega decides to get wild with the striking, I’m not sure that will help him. Zabit has shown that he can stay patient, work at outside range, & just play matador using good footwork.
And though I would favor Ortega in the jiujitsu, Zabit is no pushover on the ground either. Brian might not get the sub even if he does get a takedown.
I agree Zabit tends to fade in the 3rd though. That is Ortega’s biggest chance. It’s just not necessarily a very reliable one... how many times can a guy pull a rabbit out of the hat?
