Once a fan favorite, Rantanen is now a fierce rival following his arrival with Central Division-foe Dallas. And for the first time in his NHL career, Rantanen was a visitor in a building he’s called home for a decade.

MacKinnon’s family, Makar, Devon Toews, Andrew Cogliano and Gabe Landeskog all took part in the ceremony. Rantanen did not … but he was on the ice. He was standing near the Stars bench and tapped his stick on a couple of times for his former linemate-turned-foe.

"I told them I'll be flexible and I want to play here for a long time. Then a couple days later they traded me," Rantanen said Saturday.
