Interesting. Rozenstruik's lack of output and inconsistent takedown defense can make him vulnerable to Tybura's grinding wrestling/clinch work and pressure-boxing to the point where he drops a Decision, but honestly sometimes Tybura chooses to stand and bang with dudes in the pocket more than he should and gets clipped for his trouble. Marcin's grappling is good, but it's also not always a stifling affair that allows him to put anyone on their back reliably. Either Tybura gets put down after winning a round or two or he grinds out a grimy win via activity. Forced to choose between the two I'm sort of leaning towards the former, but I could see myself changing my mind.
As a side note: Tai Tuivasa should have gotten either of these two guys instead of Lewis rather than the UFC matching them up against each other.
