Colorado’s high-flying hockey team has run into a problem it’s going to need to solve, and that’s the defensive acumen of the Dallas Stars. The Avalanche dominated Game 3 of this second-round playoff series territorially, but not on the scoreboard. Tyler Seguin and Logan Stankoven both had a pair of goals, while Jake Oettinger made 29 saves Saturday night at Ball Arena to help Dallas prevail 4-1 and reclaim home-ice advantage in the series. The Stars now lead the series 2-1.
