OMAHA, Neb. -- The first sign the UND coaching staff was looking for more from its top-ranked team came two hours before the puck drop.
The line charts showed a major shakeup.
The coaching staff broke up the longstanding top line of Grant Mismash, Collin Adams and Jordan Kawaguchi, which stayed together for much of last season as UND ran to a 26-5-4 record. They moved Riese Gaber up to the top line with center Shane Pinto and Kawaguchi.
They also reunited Gavin Hain and Mark Senden, who have spent much of the last two seasons together. They've tried those two on different lines here and there, but always seem to reverted to what had worked in the past.
The second sign the UND coaching staff wanted more came when UND took the ice for warmups. It donned its black jerseys for the first time this year. They have been a good-luck charm in the past. The Fighting Hawks were 7-1 in them last season.
It didn't add up to a win this time, but some progress was made in a 2-2 tie with Minnesota Duluth in Baxter Arena.
The new top line gave UND a spark. Gaber scored his third goal of the season and Pinto buried one on the power play. But the Fighting Hawks weren't able to close out a late lead.
Cole Koepke scored with 4:25 to help the Bulldogs pull out a tie. The Bulldogs won the shootout to grab an extra point in the NCHC standings.
"It was about what we expected," Minnesota Duluth coach Scott Sandelin said. "We've had a lot of great games with these guys, a lot of tight games."
UND moved to 3-1-1. Its next game is Saturday against St. Cloud State.
Minnesota Duluth remained as the only unbeaten team in the NCHC Pod at 4-0-1.
Minnesota Duluth jumped out to the early lead at 7:03 of the first period on a harmless-looking play. Third-line center Jesse Jacques entered the zone up the middle and snapped a shot from beyond the dots that trickled through UND goalie Adam Scheel, who played his fourth goal in eight days.
UND turned the tide in the second period and eventually was rewarded for it. Minnesota Duluth freshman defenseman Connor Kelley attempted to exit the zone with a pass, but Kawaguchi intercepted it and took it the other way. Kawaguchi left the puck for Gaber, who picked it up, skated to the slot and wired a shot past Bulldog goalie Ryan Fanti.
Pinto gave UND a 2-1 lead with 7:36 left in the third period when he blasted a Matt Kiersted feed for a power-play goal. But the lead didn't last. Koepke found a loose puck at the side of the net and took a swat at it and it went in.
Notes: UND played its second game without rookie defensemen Jake Sanderson and Tyler Kleven, who are with the U.S. World Junior Championship team. It also played its second-straight game without forward Harrison Blaisdell, who suffered an undisclosed injury in the third period of Sunday's game against Western Michigan.
