Question re stance switching: Pereira v Ankalaev

Disclaimer: I'm a complete and total casual. Pereira (orthodox) seemed to have trouble with Ankalaev's stance (southpaw) in a few ways. In these stances, Pereira could not fire off a calf kick against Ankalaev's lead leg with full wind up. It was Pereira's lead leg against Ankalaev's lead leg. Also, Pereira seemed to have trouble finding a home for his left hook. Question: Is there a reason Pereira wouldn't want to switch stances to at least blast calf kicks from a southpaw stance? Not saying a fighter should develop both stances equally, but it seems like developing a few tools out of the non-normal stance would help a ton if the fighter's primary weapons aren't working out of the normal stance. Also, if a fighter is on the receiving end of some damage like calf kicks to the lead leg, it seems like it would help a ton to have a few tools in the non-normal stance. submitted by /u/Ozark--Howler [link] [comments]
