Hitchcock and Ruff met in the 1999 Stanley Cup Final when the Stars, coached by Hitchcock, defeated the Buffalo Sabres, coached by Ruff, in six games. Dallas won the Cup with a 2-1 win in triple overtime in Game 6, with Brett Hull scoring the game-winner despite debate whether one of his skates was in the crease or not.
In 2006, Hitchcock and Ruff met when the Sabres eliminated the Philadelphia Flyers in the Eastern Conference Quarterfinals in six games.
There have been harsh words between the two in the past, but after working together on several occasions with Canada, most recently at the 2014 Sochi Olympics, the two longtime coaches have a strong mutual respect for one another.
"Yeah, I learned a lot [by being around him], learned actually at the end to like him," Ruff said.
But the irony of Ruff now coaching the Stars while facing Hitchcock again is not lost on the Dallas coach.
"Yeah, it's a full about-face. I like where our team is at, I like where our team has got to and I'm sure he is sitting in the same place," Ruff said. "… It's not about him or I, it's about how the teams are going to play."
