Good post TS. Just to piggyback on your first point, it is generally accepted that fighters can compete at a very high level, even have an advantage, when moving down in weight. Going up a weight class is what raises the questions of being able to handle bigger, stronger fighters. And I agree with you on how Edgar will handle the weight cut.
I disagree a bit with you on leg kicks. True, Edgar is good at catching them, but he has eaten them too. And Aldo is one of the best in the business with his leg kicks. They are fast and powerful, perfect technique. He doesn't leave them out there. I am not saying Frankie won't catch one or two, but eating Aldo's kicks are an issue.
Overall great post and I agree, this will be a very competitive and a really fun fight to watch. I am not sure why people are saying Frankie can't compete. He has been great, so that thought process in unwarranted.
