Actions speak louder than words. I've heard plenty of "lip-service" over the years only to watch them continue doing the same things right afterwards...let's see them put it into action!
Before Dundon took over, I agree we saw some of that, but we haven't really seen that over the past 6. This has been the 3rd best regular season team in the NHL over the last 6 seasons combined. You don't get there by giving "lip service".
Or course they could still lay and egg the next game, but it hasn't been an issue over the past 6 seasons.
I think more of the issue is with a lot of new guys, they are going to take time to gel, particularly on defense where Walker and Ghost are completely different style players than Pesce/Skjei.
