Adegbuyi at that time had only had 1 year in kickboxing, was at the start of his career. Rozenstruik had a lot of more experience since he was fighting at that time Duut, Wilnis or Welboren.
It was the puncher"s chance, Rozenstruik was still slow as a turtle. He went after to lose 4 out of 5 fights in Superkombat, being released. Only won a majority over Falin, who is a lot worse than the other Russian-German aka Toktasynov.
Adegbuyi won the rematch by outboxing him. Adegbuyi also lost his first fight against Zhuravlev by KO, then demolished him.
Basically in kickboxing Rozenstruik has 0 important wins. Adegbuyi and Abena were at their beginning, only a draw against a 23-24 year old Wilnis is value. Fought Glunder, Pique or George in their late years, not in prime anymore..
