I don't know, I've had a hard time getting a read on Dolidze. For the longest time I felt like he was a big, lumbering oaf of a dude. Super dangerous fighter, but one with a lot of holes in his game who was better at capitalizing on mistakes from his opponent than actually imposing his will in the striking or grappling outright. Low volume, questionable wrestling, geriatric footwork, poor defense, and slow as Christmas. But lots of power in his hands, strong as an ox in the clinch, and a terrifying submission game.
Then his fights against Smith and Vettori (the rematch) made me reconsider. In those he was a lot lighter on his feet and put up triple-digit strike counts against well-rounded veterans, washed or otherwise. But then he fought Hernandez and looked as limited as ever.
If it's classic Dolidze, I think CLD probably just dances around and tees off on him like Imavov did. He's way faster and way slicker on the feet. He's also shown himself to be vicious in the clinch, which is historically Roman's favorite position. That said, it's not impossible to bully CLD or take him down. Robocop showed the blueprint for how a big, strong grappler can grind him out and I wouldn't be surprised if Dolidze is able to make it dirty and win a grappling-heavy fight. However, Roman often seems to hesitate to wrestle even when he should (or when his team is begging him to) and instead will settle on lobbing two overhands and calf kicks at range per round or just hugging his opponent against the cage for 4.5 minutes instead... so I can't rely on him pursuing the perceived path of least resistance.
I'll take CLD by Decision, but I expect Dolidze to be beaten up by the time all is said and done. He'll probably have a moment of success where he puts Duncan in danger along the way.
