I don't think it's fair to criticize any players defensively, outside of specific plays where players made mistakes (like that Crosby performance a couple of games ago). The team is definitely playing well defensively right now, and there isn't anyone off the top of my head that I'd criticize for their defensive performances. The problems on this team are all offense right now. You can criticize the defensemen for problems with the offense, but I think they're doing a good job defensively. It's just really hard to score when multiple of your top offensive players are in slumps and 4 of your 6 defensemen either have no offensive talent (Johnson and Gudbranson) or poor offensive talent (Pettersson and Dumoulin). From that POV, all of Gudbranson, Schultz, Dumoulin, Johnson and Pettersson deserve criticism.
