To be fair, we haven't had many father to son recent successes.
Stephan Matteau
Martin Brodeur (2 sons drafted in the NHL)
Claude Lemiuex
Maybe I'm forgetting others but Kasperi was atleast a half successful than the peers mentioned above.

And just f***ing weird...
Slava Kozlov is both the uncle and brother-in-law to Vladislav Namestnikov (Slava married Vladislav
s aunt, then Vladislav married Slava's sister... so it's not as weird/creepy as it initially sounds)
Also fun fact, the 2 Mike Peluso's were first cousins.
