Just to be clear that they are competitors now, Sullivan didn't hesitate to throw the first soft verbal jab of the series at his counterpart during an in-game interview with NBCSN's Pierre McGuire midway through the first period.
McGuire asked Sullivan if he was impressed with how the Blue Jackets, who had a 16-3 edge in shots on goal in a 0-0 first period, were getting the matchup they wanted against Sidney Crosby's line, i.e. putting Brandon Dubinsky out against him despite not having the last change.
"Listen, any coach can get any matchup if they want to run to the bench," Sullivan told McGuire. "That's their prerogative. We're just going to play the game."
It was harmless, really, but you wonder if these two close friends will pull out the heavy artillery at any point in the series. If they do, it'll be out of competitiveness, not animosity or disrespect.
"Working six or seven years together through some good times and quite honestly you become even closer through adversity," Tortorella said. "I've learned a ton from him."
Sullivan said the exact same thing.
"One of the reasons why I joined his coaching staff was to work beside him and try to learn and grow as a coach and as a person myself," Sullivan said. "Torts is a guy that's had a lot of experience. He's had success. He's won at every level he's been at."
Their relationship started long before they became co-workers with the Lightning during the 2007-08 season. Tortorella was an assistant with the then Phoenix Coyotes and Sullivan was a player during the 1998-99 season. They would talk hockey non-stop.
Years later, Sullivan joined Tortorella's staff in Tampa Bay. Tortorella was fired after the 2007-08 season and sat on the sidelines for the first three quarters of the 2008-09 season before getting hired as New York Rangers coach on Feb. 23, 2009.
