That is a fair sentiment.
I still say he pulls a Gaborik as he is far more similar to him than any other comparison. Guys who had proven the talent not just to produce in the NHL but produce very well. On top of that, Semin's bouts of lazy play has caused people to falsely label him a "bad" defensive player. Go look at his Coris stats, (even from last season) go watch him actually play. When he isn't lazy, he back checks, he is a solid stick checker, he can kill penalties. He has done all those things well. He doesn't lack the ability to do them. It's his motivation.
But like Gaborik, Semin knows this is his last chance in the NHL. After being traded to LA it was the same deal for Gaborik. If he didn't perform, his time was likely done. If Semin WANTED an easy out, if he was looking for the lazy play, he would of returned to the KHL. He got bought on a huge deal, the only incentive for him to stay in the NHL is to win. But to stay he'll have to stop being lazy.
You'll get at least two hard working seasons out of him, and I'd put my money on that.
