You will have to expand on Freddy was Jack before Jack - I'm not sure what similarities exist. Also not sure how being a back up to a good goaltender speaks volumes. As a GM you're looking for consistency and reliability in net year in year out.
We can forget about forward depth. You can only spend so much on forwards. A cap split of 55/20/7 (F/D/G) is about as high as you can go wagering on offensive power.
We have 40M tied up in four forwards, you get 15M more to spend under that structure on the remaining eight. You can't have more.
You will have to expand on Freddy was Jack before Jack: This to say Freddie Andersen was a scapegoat of another kind. Wasn't clutch when he needed to be, etc, etc. And I defended Andersen. But he was absolutely lambasted as not being the guy. He couldn't make one more save, etc, etc.
Jack Campbell despite putting up very good playoffs performances has been criticized exactly the same way. It's not the lack of scoring from our offense, it's Freddie or it's Jack.
On being a backup to Kari Lehtonen and Jonathan Quick. Well...Net management being what it is, when you've got nigh best of era goaltending in front of you, the kid with a lot of potential isn't about to unseat the proven winner. It's another way of saying, but for goalies at the top of the league, Campbell likely gets longer looks earlier in his career.
We can forget about forward depth: Well, we're going to have to find a way. Maybe Douglas is our new 4C. Maybe Kniess makes his debut earlier than expected. Whatever the means is that we begin to fill out our depth, the one thing we can't do is hamstring ourselves by using assets on positions that can be had (ie signed) for free.
With respect to the cap, I agree. But it affects what we can do in terms of signing a goalie. And signing the cheaper of equal options is the only sane action to take. Which brings us back to Gibson; We're thin at depth, compromised at cap, so rather than sign a cheaper Campbell, Husso, whomever, we move out limited assets and take on greater cap?
We have 40M tied up in four forwards: Exactly. See above.
