The last time he played in North America was 3 years ago. And even then he only got to play 9 games.No need to prove you wrong anymore since his time in NA has already proven you wrong. You could try to make a case why he iswhat you say he is, just for funnsies. Because his skating is below average, size ok but not exceptional, offense almost nonexistent on NHL level.. Players like that really have to catch a good break to get into the NHL, sadly it didn't happen to Kulda.
I think you're missing the fact that he has improved while playing in the KHL. Both in terms of offensive capabilities and defensive positioning.
Just watch the Latvian games and see him starting a number of attacks and showing initiative at the other end. That wasn't what Kulda was doing in 2011.
