Why not. His full career prior to Edmonton 71-39-14, 2.53, .916. Playoffs 6-8, 2.45, .915
Skinner so far 66-33-9, 2.68, .911. Playoffs 5-6, 3.68, .883.
That not generously comparable, it's very comparable, possibly even favorable with the only thing really going to Skinner's edge being that he's significantly younger than Campbell was the time of achieving those stats (which is a major thing).
By no means, am I suggesting he should supplant Skinner, just that the narrative of him only being good for a brief period of time in Toronto is highly exaggerated. His biggest issue has been consistency, but when he's been on, he's generally good for an extended period. And in some of those periods where he was "on", it wasn't like he was playing behind the early 2000s New Jersey or Dallas in terms of defensive play. Look at those LA teams... woof, woof, and even though Toronto fans like to claim Matthews is like prime Bob Gainey defensively, that team has never been overly strong at defense.
