"It's disgusting. It's bad. It's bad right now. We need to change this around ... something's gotta change here," Tkachuk said postgame. "We've gotta get back to the old us and get out of this little funk we have here because this is not fun."
The Flames dropped Sunday's contest 6-0 to the Vegas Golden Knights and were blanked by the Arizona Coyotes on Saturday, marking the first time since 2009 that they've been shut out on back-to-back days, according to Sportsnet Stats.
"It's getting pretty old," Tkachuk added. "We just can't get this lead. We trail, we press, and they put a six-spot up on us when it's a pretty tight game until the third period.
"We just kind of let them run away with it and leave our goalie out to dry countless times. It's getting old."
The Flames own a 10-10-3 record this season and currently sit in fifth place in the Pacific Division.
