They may or may not need a new voice, I can understand that argument, but Bednar definitely outcoached DeBoer. Not the other way around.
With his gameplan, and adjustments, the Stars didn't stifle their breakout in any game, didn't prevent them from getting scoring chances, and didn't get many themselves. 5v5 the Avs were definitely the better team based on the eye test and analytics.

The Avs lost the way they always do. Preventable mistakes at key times, bad shot selection/accuracy, and special teams.
Even though both special teams were among the absolute best in the league to end the season. PP was 1st in the NHL the last 33 games, and the PK was 4th in the NHL the last 60 games, including a 40 game stretch where they were tied for 1st.
If they don't give away three 3rd period leads, they beat the Stars 6 out of 7 games. The players gave it away.
