here. Given how he attempted it a couple of times makes it seem deliberate (and not just swinging wildly) so maybe that 'fake the jab' was code? Or just something Hendo figured he'd do on the fly.
But if he can start committing to other strikes and getting his opponent's attention shifted away from his right hand he can open up more opportunities to land it. He's pretty predictable but he can use that to his advantage if he starts mixing t up. He's two big wins away - (or one win over the right opponent at the right time) max from a shot, I reckon.
