Lessons from the past week of play in the NHL:
• This isn't Logan Couture's season — and it won't be the Sharks' season, either. Playing his second game after recovering from a broken bone in his leg, the skillful forward left San Jose's game at Edmonton last Wednesday because of what was determined to be a small arterial bleed. Couture underwent surgery the next day and is out indefinitely, though likely not long term. An absence of any length hurts the Sharks, who are 3-6-1 in their last 10.
• Steven Stamkos will be in for a busy time Tuesday, when the Tampa Bay Lightning plays at Toronto. Stamkos last week "liked" a tweet linking a video that discussed his chances of signing with the Maple Leafs as a free agent next summer, spinning Toronto fans and media into a frenzy. Stamkos "unliked" the tweet but the storm it spawned is sure to hit ridiculous heights when he plays in the Center of the Hockey Universe.
• Trips to Alberta are becoming perilous. After the Edmonton Oilers gave a nod to their past last Friday by honoring former coach and general manager Glen Sather, the architect of their Stanley Cup dynasty, they provided a glimpse of a promising future with a 7-5 victory over the New York Rangers. That capped a 5-0 homestand. The Calgary Flames faced the same teams--Dallas, Boston, San Jose, Buffalo and the Rangers—and also went 5-0.
