The success in multiple weight classes is a bit iffy to me. He fought Dustin and got spanked, then he fought Justin, who has never been a champ (the BMF isn't real).
Meanwhile, Volk fought Islam twice, and was competitive as fuck in the first fight. There's an astronomical difference between fighting Islam and fighting Justin.
So Max has one win at LW, unless you're counting pre-UFC, but even then, Volk has more wins across more weight classes than him.
He has all his strike records because he basically went 5 rounds 8 times (almost 9 with Gahtje) in his last 10 fights, and isn't much of a finisher at the highest level.
Having the record for most strikes absorbed isn't really something to be proud of lol.
Not saying Max isn't amazing, but some of it is too hyped for me. I just see Volk as a much better fighter who did it easier.
