There are about 37 Russian players in the NHL, some of them are top talent: Dats, Ovi, Malkin, Kovy and many others, so if out of 37 players 5 players have somewhat questionable work ethics - it's easy to call rest of them "lazy", however it's not always true and if you take any nation and look at their players with questionable work ethics you will probably get the same percentage (US, Canada, Finland, Sweden, Czech Republic); but as far as Russians - they've had some vivid examples: Yashin, Kovalev, Radulov, etc.
Would you call Kovalchuk lazy? He is always in top 10 point-wise, had a decent run in the playoffs, but few years back everyone was taling that he is extremely selfish and lazy.
I personally would be thrilled to have Semin; I think the whole Red Wings team mentality and dynamics, in addition to Dats influence would make him extremely good player for us.
Hey, and remember many of you called Dats playoff bust a few years ago?
