I don't know if our D looks that great. Look at the holes we had last year. Matheson and Savard out in a few years and you're left with Guhle and hoping Hutson/Reinbacher become studs. Mailloux not sure he's more than bottom pair and Harris/Struble are ordinary. Arber is at best a top 4. So, no, we are far from the defense like Vegas, Dallas, Hurricanes, etc.
Imagine if you add Buium/Dickinson to Reinbacher + Hutson, that's a big 3. Then add Arber that's a much more elite defense than what we are hoping right now.
While up front, you can build around Slaf, Suzuki, Caufield and Dach. Then you get another asset through trade or FA to complement them. It's possible
