We have seen from Aldo's previous fights that his right leg is the source of his successful ultimate leg kicks which works impressive against orthodox fighters. And this is also the reason why he has able to control the distance, as suggested by his previous challengers. With McGregor it's different. Not only that he switches stance regularly, but his standard stance is southpaw. This is also how he controls distance as seen against the Siver fight. Normally, Siver is very good in cutting distances but it didn't work well against McGregor. Aldo will have to switch his stance regularly as well if he wants to implement his leg kicks or stay with his base stance and go for the inside leg kick. But that is dangerous for him because he will be vulnerable to McGregor's strongest weapon which is his left straight. This means that Aldo will have to resort to other skills such as his wrestling and grappling. Of course, he possesses a variety of skill sets but we know that his striking was only effective whenever he starts controlling the distance. Aldo's last performance is at sub-par to his usual self. Should he fight the same, I doubt if he can survive the punching power of McGregor once his fist landed or even with his back heel kick.
