Boldy isn't a comparable whatsoever, near the exact opposite. He signed his deal with less than 80 games under his belt, still on his ELC.
That's what happens on ELC deals, you pay for the future, not what he is now.
With DBC, you're paying what he is now. Will a team in UFA possibly fork over 8 million? Maybe, but I don't think he's valued around the league like he is on here.
If we are paying 8 million for DBC, we will likely regret it soon thereafter with the roster construction as is.
Fiala is the closest comparable, at 7.8, and is without a doubt the better player.
