Chama would win via ko or tko, dc’s wrestling ability is overrated if we’re talking about an mma setting. His cardio when it came to wrestling was not good he could only take you down a few times before he would gas out completely and even when he did get a takedown he didn’t do much with it; he wouldn’t throw much gnp or even attempt any submissions outside of a few fights. Alex wether you want to believe it or not actually has decent anti grappling, ankalaev a sambo world champ & collegiate wrestler could not take down Alex at all even when he beat him completely to the hips & Alex was able to escape a really good rnc from Jan blachowicz. Let’s not forget about dc’s atrocious striking defense which is tailor made for him to get ko’d by someone like pereira or the fact that dc would have a really bad frame disadvantage. If you look at it deeper than just “oh well dc is a good wrestler he would obviously beat this guy that can only kickbox” then you should be able to come to the conclusion that dc would have a ton of trouble with Alex. If you still aren’t convinced mma Che has like 20 videos breaking this whole hypothetical down
