Chip McCleary on the waiver period (he's talking about the 2007-08 season, but the principle is the same):
"
Q: How long is waivers applicable?
A: The waiver period starts from the 12th day before the start of the Regular Season [for 2007-08, the start of the Regular Season is October 3, 2007 – the games played in London do not count as the start of the season] and end on the day following the last day of a Club’s Playing Season [which means that for playoff teams, waivers may still be necessary while the team is playing; generally, this would apply only to re-entry waiver requests]."
And from Spector:
"Surfing through the last news reports out of Dallas, I noted that the Stars had yesterday recalled forward Toby Petersen but he'd have to pass through re-entry waivers.
Usually during the season a team can claim a player via re-entry waivers and only have to pick up half his remaining salary. However, there is an interesting twist to the rule after the trade deadline has passed.
As per Mike Heika of the Dallas Morning News:
The process involving re-entry waivers changes after the trade deadline, as a team can claim Petersen for half price and place him on their NHL roster, but they cannot play him in the regular season or in playoff games for the remainder of the season. That allows teams to make call-ups like this without much risk of losing a player.
Pretty much ensures that a team can safely recall a player via re-entry waivers without fear of losing him to another team from the day after the trade deadline to the end of the season and into the playoffs.
Just goes to show you learn something new about the CBA every day!"
So, waivers remain in effect, but no one can claim a player and play him in the NHL after the trade deadline *this* year, I believe. That is to say, you have waivers but no waivers, really.
