I like your analysis, and I don't want to be that guy, but since Cruz and Edgar are some of my favourite fighters, I need to say
1.
This is not a darting straight right—he's using the crouch to get reads off of faber and also gets fabers attention on his right hand while he loads up on the left.
2. As for Frankie, I know he didn't show it in his last fight against Aldo, but he had more success wrestling Aldo in the first fight than any fighter ever has, including Mendes:
Also, while Edgar and Dom are very similar in theory—both rely on feints a lot to get reads off their opponents, both have great ankle pick takedowns and great reactive takedowns etc etc—their execution of those techniques are very different, so I wouldn't say that Edgar's lack of success against Aldo is any real indication of how Dom would do against Aldo.
