... is an example why people question drafting russians.
I don't think so.
Kovalev was a good professional and he was working carefully on his game during the practices. Unlike Semin, for example, Kovalev really wanted to win, he was a leader in the playoffs. The sequence involving Souray and the slashing is the exception, not the rule, I think (we came back in this series and Kovalev was a big factor).
Of course we could debate on his inability to get motivated for each game, but this is a complex psychological problem. Thing is, his salary reflected this inability, 4,5M was fair.
