Campbell's not going anywhere. That's a hard reality people need to accept.
It is deeply troubling when your big money/term free agent signing needs to be shutdown essentially immediately in his acquisition for a complete rebuild of his technical and mental game along with equipment. Campbell is emerging as a goalie that won't steal hockey games but the team can't afford to cost them games with critical time weak and leaky goals. It's been a pattern and this team sags a lot when it happens.
Now the big picture. We won't have a true read on Campbell until a very limited uni-dimensional platoon defense is significantly upgraded with top two pairing defenders, faster processing, smart and efficient puck moving type and optimally a quality veteran stabilizing goal suppression type. Current defense is erratic, prone to both unforced own errors and under pressure by aggressive, hard forecheck. The system play does not align with the platoon defense who can't consistently zone exit with stretch bombs that get picked off to create own zone or neutral zone rush opportunities against. Minus a #7 career minor league platoon guy, this d-corp is soft in net coverage, often chase opposing forwards outside of high scoring ice, and not strong enough in cycle breaking and physical defending areas of the ice. They're taught (?) to move out of shooting lanes to let their goalie see the puck and stop the puck instead of blocking shots from range.
The own zone support from forwards waves erratically as the hard effort to backtrack is not applied as it is to chasing scoring opportunities in the fun zone. Both forward and d like to chase opportunities to add more scoring in key situations when shut down mentality and that disciple is what elite teams have learned wins games in the second season.
Until all of these personnel, systems, and systemic issues are worked out, the goaltending position solely can't fully and completely be held to account on a team that still has distance to walk amidst the truly elite teams in this league.
