NHL power rankings: Another week, another late-season coaching change with Isles swapping Roy for DeBoer

Key Points:

• The Toronto Maple Leafs recently fired GM Brad Treliving, reflecting a trend of late-season coaching and management changes seen with teams like the Vegas Golden Knights and New York Islanders seeking a "coaching change bump."
• The current NHL power rankings place the Colorado Avalanche at the top, with strong performances from key players like Kirill Kaprizov for the Minnesota Wild and Cole Caufield for the Montreal Canadiens highlighted as pivotal for playoff success.
• Several teams are in tight playoff races, including the Buffalo Sabres, Pittsburgh Penguins, and Philadelphia Flyers, while others like the Florida Panthers and Vancouver Canucks have been officially or effectively eliminated from contention.
• Coaching changes have had mixed impacts, with the Vegas Golden Knights winning their first three games under new coach John Tortorella, while the New York Islanders replaced Patrick Roy with Pete DeBoer in hopes of ending a losing streak.
• Some teams face critical challenges ahead, such as the Detroit Red Wings' recent poor performance and the Calgary Flames' potential to secure a top-five draft pick, signaling significant rebuilding phases across the league.
