Avs have and always will be an offensive minded team, even in that latest Zadorov interview, he said that Roy wants his team to be offensive, so while Beauchemin and Zadorov will definitely help the defense, i think Avs will still take tons of chances in the offensive zone, they will never be a trapping team and still give up a lot of shots.
People fail to realize that it's not just having bad or average d-men what made the Avs defense bad, it's also the system, relying heavily on the goalie. I mean that's no secret, last year Roy himself said, he doesn't mind giving up all those shots against because they know Varly will make the saves.
Hopefully that mentality has changed in Roy, although he's still thinking offensive, they really need to cut down the shots against, because even if Varly is making the saves, all those shots against gives the opposition a momentum.
