volk = smaller man, great striker with good wrestling, physically strong, known commodity, perennially underrated, beat everyone on the way up, proven heart and chin
islam = larger man, great wrestler and decent striker, hasn’t faced many challenges on his way up, relatively unknown commodity, questionable chin
the main problem i have with betting on islam is that he hasn’t faced the sort of fighters that would give him problems (except perhaps, arguably, charles). like khabib before him, his best wins are either over people who don’t represent much of a threat overall, or aren’t equipped to handle this level of mma wrestling. he has looked good in those fights, but they went pretty much how you would expect them to go. volk by contrast has answered many questions about how he faces adversity, and the styles that give him trouble. what we know is that he always rises to the occasion, and he prepares quite well. we’ve seen volk in trouble, but work his way out. we’ve seen him change things up on the fly. idk if islam is capable of that because until now (except for his loss) his fights pretty much go as planned. in the future, maybe people will start more seriously preparing to deal with dagestani wrestling and sambo. idk. but right now it does seem that most fighters are unprepared for it.
