"We're young back there, so getting a little more experience is a good thing," Nill said.
Play ramped up in the preseason, and the regular season is expected to be even more intense, so providing a player who can adapt to that is key. Plus, Carrick is a different option than Polak. Listed at 5-foot-11, 195 pounds, Carrick is a puck moving defenseman who uses his skating. Polak is listed at 6-foot-2, 240 pounds and is seen more as a physical force.
That could mean that Carrick will be a good fit against the Stars' first three opponents -- Arizona, Winnipeg and Toronto.
"He's first of all a character player," Nill said. "He has a great work ethic and he fits what we want to do. He's a good skater, good puck mover. He can be a real solid player for us."
The native of the Chicago area played in the U.S. National Development Team program and was a fifth-round pick of the Washington Capitals in 2012. Carrick was traded to Toronto in 2016 and was in the regular rotation with the Maple Leafs the past two seasons.
"He's a very good option for us," Nill said. "He's a big fitness guy. He's very committed, business-like. I think he will definitely help us."
The Stars also put winger Remi Elie on waivers Monday with the intent of sending him to the AHL. That means center Roope Hintz will be on the opening-night roster. If the Stars place Martin Hanzal and Johns on IR, and send Bayreuther to the AHL, they should be down to 14 forwards, seven defensemen and two goalies by Tuesday's roster deadline.
"We feel good about where we're at," Nill said. "We feel good about our depth, and we're ready to go."
