Except it is really not. Because if that were true, Andersson would have done much better in the NHL. Especially since Calgary's defense is superior to ours.
And let's assume what you say is true. I like Dermott a lot, but we already have one. This team needs more than another Dermott playing 16 minutes on the bottom pairing to be successful next year. We have guys who can play at least 16 minutes already in Carrick and Ozhiganov (possibly Holl and Rosen too). The problem is, this puts us in a worse position last year because we have a huge hole on the PK without Polak and one less guy who can take pressure off of the already swamped Hainsey and Zaitsev, assuming Andersson is like Dermott.
I feel like there is something going on beyond this conversation... Because this is pretty irrational for you.
There are more than a few guys who are good enough, and we have the assets to acquire, but no I am not going to settle for overpaying for less than ideal fits. If I am overpaying, I am at least getting a guy who provides serious value to this team next year and for many years to come.
