I'm not certain that particular 767 has a stick shaker but I'd be surprised if it didn't. My concern with any cargo airplane crash is weight and balance, was center of gravity in the normal envelope, and did anything shift during turbulence? That shouldn't happen, but if it does, it can really adversely affect stall avoidance and recovery. From the look of the grainy surveillance video of that crash, it could be stall crash, it does vaguely look like they might have been recovering but flat out had insufficient altitude. Also with respect to MCAS, it's not a factor when the autopilot is enabled, as the autopilot shouldn't permit approaching the edges of the normal envelope with such a high angle of attack that the MCAS routine would apply. I haven't read any report about whether the autopilot was enabled or not; let alone the exact sequence of modes enabled and disabled. So the autopilot itself can't be excluded as a suspect until there's evidence it was a non-factor.
