Malykhin is a very physically strong wrestler with heavy hands, a low center of gravity, and great footwork. That is the absolute worst stylistic matchup for a lanky BJJ fighter like RDR with questionable standup.
RDR looked bad because of Anatoly not because he isn't a world class fighter. If he were fighting in the UFC/Bellator he would be fighting at 185lbs (Middleweight), as he did on the regional scene, not ONE LHW which is 225lbs.
RDR is a better version of Andre Muniz. Don't be so quick to write him off because Malykhin, who I think would give Ciryl Gane trouble, destroyed him; it happens.
