Is fatigue getting to Frolov?

Following his amazing 11-game period (13th November against SJS through 7th December vs Nashville) where he scored 11 goals and registered 5 assists, Alex Frolov seems to be cooling down a bit recently. Not that any player in the league (barring Ovechkin, perhaps) could keep it up for a prolonged time.

However, not only has not scored in the last five games (three assists to his credit), but also the number of his shots taken per game has dropped considerably (to 1.6 sh/gm). At the same time, Frolov is seeing a considerably less TOI during the last five games. He logged 15:49 and 13:47 respectively in the recent home-and-home series with San Jose. In the previous 30-odd games this season, he has seen less than 16 minutes of ice time only once, while frequently playing for 20+ minutes.

I'm not looking down on him in any respect. On the contrary - his 11-game scoring binge only sharpened my appetite for more of the same from Frolov.

So, do you think all this is a sign of mid-season fatigue? Is coach Crawford seeing it and is this why he sends him out less frequently lately (number of shifts per game is down as well)? Is there any on-ice evidence in his intensity of play?

Hmm, I'd love to hear from you on this one.
