A) No, you didn’t. You highlighted a part of sentence and asked why you should care about my opinion.
B) The numbers aren’t wrong. Superficial interpretations often are. The numbers don’t proclaim to accurately identify the overall quality of goaltenders in the league. GSAx and the likes contain more info than old stats, but they know their limitations.
See - now you’re asking to explain. I don’t have much time left, but Gibson is a good and somewhat extreme example of how statistically equal shots aren’t statistically equally impacting a goalie’s stats. Gibson‘s main weakness, compared to most modern goalies, is lateral mobility. He’s good (probably closer to elite) on first shots, great angles and reflexes, works well through traffic, good rebound control. But if your defense is prone to allowing cross-ice passes near the hashmarks or below, he’ll tend to leave more net exposed than most. Considering the (expected and factual) SV% on first shots is high to begin with, there’s not much ground you can statistically make up on these shots. If you’re playing on a team that struggles to prevent plays where you underperform the statistical expectation, that’s going to create a problem for your statistical bottom line - and the team’s success.
A team that feels confident in the defensive structure and their ability to defend those plays better and redirect the shot source, can absolutely see him as a guy who can help. Especially come playoff time, when teams tend to be less cute and default to taking clean shots more often than before.
