The NHL lockout was expected to impact NHL players in the first half of the season.
While many players chose to compete in European leagues, many others did not. There was a very limited training camp and players reported to those camps in varying degrees of physical fitness.
Even those who took care of themselves very well were not playing NHL games, so at the very least, timing was going to be an issue.
Players seem to be performing above expectations.
However, referees and linesmen are having some trouble. While you can always pick out bad calls, some have been egregious.
One blown call by a linesman seems to be one for the books while referees seem to happy to call goalie interference—even when none exists.
