The 29-year-old Mitchell is in his second season with the Avalanche, and has 25 points (eight goals, 17 assists) in 66 games. The versatile forward is currently centering the Avs’ second line with Gabriel Landeskog and Nathan MacKinnon.
“John is a proven NHL player who has been a very good addition to our team the past two seasons,” said Avalanche Executive Vice President of Hockey Operations Joe Sakic. “He can play in different situations and we feel his presence and his versatility will continue to strongly benefit our team moving forward.”
Mitchell’s three-year pact will see him make an average of $1.8 million per season.
Berra was acquired at the trade deadline from the Calgary Flames in exchange for a second round selection in the 2014 NHL Entry Draft. The 27-year-old Swiss netminder has appeared in 26 games this season (his first in the NHL), all for the Flames. He has a 2.95 goals against average and a .897 save percentage.
“As I mentioned when we acquired Reto, we strongly believe in his abilities,” said Sakic. “He has size and skill and will help solidify our goaltending position for years to come.”
The average annual value of Berra’s deal will be $1.45 million.
