Since Couturier entered the league in 2011, he has caused havoc for the opposing team's top line. One player that Couturier has absolutely frustrated is Evgeni Malkin. Malkin, one of the top players in the league, tends to lose his head and get knocked off his game when matched up against Couturier.
This all helps to explain why Malkin's wikipedia page states Couturier is Malkin's father and "owns" the Russian forward. It reads, "Evgeni Vladimirovich Malkin was born on July 31, 1986 in Magnitogorsk, a Russian city in the Soviet Union to Sean and Natalia. Evgeni's father Sean Couturier (In which Evgeni is owned by) was a pro hockey player."
