Sorry this piece isn't quite as timely as it could be: it was supposed to go in the Wall Street Journal but ultimately missed the cut...
In 1998, the NHL gave its players almost three full days off before restarting the schedule after the Olympic Games in
NHL teams fear that allowing their players to play a handful of extra games in the Olympics will hurt them later in the season or the playoffs. While it’s not clear that that happens, players do suffer when they’re not sufficiently rested. In particular, it takes players at least three days to recover and get as much ice time as they got before the Olympic break:

That’s not a huge difference overall – one less shift in their first game back. But it doesn’t mean these players are effective yet. Their teams suffered significantly after they returned:

And it’s not because other players were on the ice: the average Olympic hockey player who played in a medal game had a significant drop in his +/- upon his return to the NHL. Teams and players may not be hurt over the rest of the season, but they sure suffer in the first few days back.
