Two days before the Avalanche faces Nashville to begin a Western Conference playoff series, Colorado’s Colin Wilson already has a gripe with the Predators’ Colton Sissons.

Sissons owes Wilson money — this month’s rent for living at his home in Music City. If Sissons doesn’t pay up by Thursday, Wilson will take matters into his own hands.

“You’ll know if I cross check him,” Wilson said with a grin Tuesday after practice.

Truth is, Wilson and Sissons are former teammates and good friends. Wilson, 28, played his first eight NHL seasons with Nashville before being acquired by the Avs in a trade last summer. He made a business decision to not sell his Nashville home and rented it to Sissons, 24.

“He was one of my good friends on the team. So I let him have my place,” Wilson said. “Nashville is booming so from a making-money standpoint, I’ll be holding onto it for a bit.”

Wilson is one of three former Predators playing for the Avs. Rookies Sam Girard and Vladislav Kamenev played briefly for Nashville. Related Articles Avalanche’s Cale Makar wins Calder Trophy as NHL rookie of the year

But Wilson and Sissons won’t be buddies during the series.

“It was weird the first game back in Nashville — weird being on that other side. But I got to play two games playing there and I’m used to it,” Wilson said. “In playoff hockey, there’s no friends out there. And yeah, things are going to get heated and I don’t think anybody’s going to be laying off the other person because they know them (personally).”

The Preds advanced to the Stanley Cup Final last year and they’re favored over Colorado, in part because of their postseason experience.

“It’s not always the most experienced team that wins,” Wilson said. “Yeah, them going to the Finals — it gives you a bit of the thirst to win it, but I don’t know if that necessary matters.”
