During the Blackhawks fan convention last summer, Artem Anisimov was asked by a reporter for his thoughts on the possibility of Russian collusion with Donald Trump’s presidential campaign. “First time I hear about it,” Anisimov said, entirely serious. “I don’t read newspapers. I probably disappoint you.” Hockey players, like many pro athletes, often live in a bubble, where all they focus on is the next game, and when the bus leaves for the hotel. That head-in-the-sand mentality is especially useful at this time of year, when the NHL trade deadline looms over everybody — particularly players on teams such as the Blackhawks, who are obvious sellers ahead of Monday’s deadline. So, no, Anisimov hadn’t heard the Sportsnet report that his old team, the Columbus Blue Jackets, had inquired about his availability.
