When people are talking about the defense and singling guys out, it bothers me. It's a unit. A unit that lost two guys who ate plenty of meaningful minutes in Graves and Severson, and has since lost a 3rd in Dougie. It takes time to grow accustomed to one another, and to read and react off each other. To think it just happens right away is hopeful at best.
Just because they are the more experienced players doesn't mean that their increased responsibilities as a result of the changes to the unit itself doesn't wear on them in some capacity. Doesn't mean that you can't be disappointed in how they've performed, but it's a very real factor. Siegenthaler has been the most disappointing to me. Bahl has struggled, but I expected that could happen and I feel Marino has attempted to cover for him a great deal given they've largely been paired together.
Hopefully Miller's return will help stabilize things a bit. Maybe allow him and Luke to stay together, and move Bahl with Nemec and Siegenthaler with Marino? What could it hurt?
