I'm not sure why your stating that the Defense has been struggling? I think Timonen, Coburn, Carle, and Meszaros have been solid since Pronger has been on IR. Bourdon is also playing relatively well for a rookie. It is hard for me to believe Laviolette sets up a different game plan for the team D as well when Bryz or Bob are in goal. The difference between the two goaltenders is that Bob is laterally quicker, and has learned to smother the puck preventing juicy rebounds. On the other hand, Bryzgalov hasn't been reading the plays as well as Bob, once his positioning is off, he is finding himself not able to control the rebounds. Those pucks are bouncing off his defenders or the opponents are quickly shooting them into the open net. There was a period of time last season when Bob had a difficult time as well, he was giving off big rebounds, and he was dropping down too fast and the opponents started to shoot high for goals. Bryz will turn his game around, he just needs some time right now to work with Reese.
