You increase the probability of scoring by getting as many chances as possible.
Relying on a 50-75% conversion rate gets you where the Kings are this morning.
I think the point is that while a sweep is never 'close' each individual game saw the Kings with an opportunity to win that they did not take advantage of. It was all in different ways, which is one of the reasons it's so frustrating, and it's certainly no moral victory, quite hollow actually, but in terms of competitiveness, it was a lot tighter than a lot of other series.
I certainly don't question the heart of the guys out there, that was a war more than most of the other series. It's okay to say they just aren't
good enough. That's what makes me more comfortable with moves being made now, I don't think they had 'more to give,' they were just shut down by a better, more opportunistic team that took full advantage of every big moment. GBH called them 'bounces' and I often do too, but think of those times--Brownie whiffing open net, Kopitar shanking wide in OT, Kopitar manhandling everyone on the ice and going to the net with dudes on his back only to get stuffed by Fleury. They were better in general AND more clutch. Any of those go in, and this is a series--not sure you can say that when other teams are getting TDs put on them.
Again in the grand scheme of things it doesn't really matter because it's a sweep, and it's a frustrating one from a "take advantage of your chances" perspective, and I agree with you that those chances get magnified when you create more. Kings had the heart, but not the finish, nor the skill to create more opportunities to finish (although some of that was systematic as well, which is where Stevens gets shared blame).
