No, my argument is he’s been more bad than good and we don’t have a plan B should he completely flatline like he did in last years playoff.
One reasonable measure of consistency for goalies is the Quality Starts % (QS%) stat that Hockey reference tracks. This has been around for a while and it is a modification of a stat used to evaluate baseball pitchers. A quality start is one where the goalie has a sv% above league average or if not at least .880 with 2 or less goals allowed.
For what it is worth Skinner has a QS% of .605 this year and had a QS% of .604 last year. His career QS% is .586. For comparison this year Hellebuyck has a QS% of .675 which is actually terrific for a starter. His career QS% is .582.
Demko this year is .659 with a career QS% of .571. Saros this year is at .500 this year but for his career is at .604.
Shesterkin had a QS% well over .700 in 2020-21. But that dropped to .604 last year and is at .543 this year. That parallels his drop in his sv% from .935 to .916 and now at .901. Adin Hill this year is at .711. Such numbers tend to reflect Vezina quality goaltending and are actually quite rare.
In 2020-21 Smith, who was terrific that year, had a .633 QS% which was his best of his career. His over all average was .534.
Why does this matter? The reality is that a team with a decent to very good offense will win the vast majority of games a goalie gets a quality start. This year for example the Oilers have won all but one game when Skinner has a had a QS. The exception being the last Vegas game which with any puck luck they may well have won. The only loss that Pickard had a QS was vs Carolina. Overall you can expect the Oiler to win 90%+ of the games you get a QS from one of the goalies.
Top offensive teams win a fair number of other games so the QS% is a lower bound for a team's expected win rate. (In fact, Oettinger has a QS% of .455 this year (and a sv% of .04), the lowest of his career by far. Dallas has bailed him out a lot this year by outscoring many of his bad games.) So a starter with a QS% of close to .600 is going to give his team an excellent chance at making the playoffs comfortably.
People can comment on Skinner's skill set. I don't profess to be any sort of expert on goalies. But in the end the goal is to stop the puck. The more you do that the more your team wins.
