That "very very poor sub par overworked defense" does just fine with Stuart Skinner. I have no love for our defense but they're just an average to below average NHL defense, and shouldn't be treated as any more nor any less. They're not some Anaheim/Chicago level dumpster fire. Jack Campbell is the problem. Suggesting otherwise is ridiculous.
Again, our defense is no juggernaut, our forwards love to cherry pick, our systems often break down into hail mary stretch pass coinflips, and many of the defensemen have numerous warts and are played in spots too high for their abilities. But none of that makes them anything worse than a slightly below average NHL defense. Stuart Skinner plays under the exact same conditions, against stronger opponents, with the team playing worse eye test wise in front of him, yet still sits slightly above league average with a 0.913 save percentage and right around league average with 2.95 GAA. Jack Campbell is insufferably bad.
