Krueger indicated that a primary focus of his is defense. Works for me. And he apparently has Bot's ear. But Risto has to go. As long as he's been in the league, to state, as he did last season, that it's still difficult to figure out what he should be doing defensively, says it all.
Also, we may discover we have decent goaltending once the defense is clearly fixed, which includes forwards helping out. Being outshot every game tends to wear, no matter who the goalie is.
And good defense starts with the forecheck. We've neglected good, effective forechecking for years.
