respectfully disagree
last year it was
this year we will see a dramatic improvement.
If you'd swap "will" with "might" i'd tend to agree, but quite a few things would have to break our way for that be a reality. Unfortunately, things could easily break the other way too
ADA keeps it rolling <-or-> ADA struggles to stay in the lineup
Brady Skjei meets his potential <-or-> Brady Skjei continues to disappoint
Fox can play meaningful minutes <-or-> Fox really struggles at the NHL level
One of Rykov, Hajek, etc, nail down the LD spot <-or-> No one really stands out as an obvious choice
The swapping of Trouba and Shattenkirk is a universally accepted positive, but pretty much everything else is TBD
Hence, to me at least, our defense is a tire fire until we've observed otherwise.
