it's highly, highly unlikely unless somehow all of those extra goals came in clutch situations *and* the team was able to further capitalize and do something with said goal (as we've seeing twice lately, tying a game late in the third doesn't always translate to a point). what's more likely is that many of those goals have no effect on the outcome of the game, for instance coming in a game that was already blowout win or a blowout loss. everyone seems to assume that even a mediocre powerplay is going to come up with clutch goals all the time.
also, the team is one of the worst 5-on-5 and PK teams in the league. maybe if they didn't suck at *everything* they'd be in the playoffs. i don't get the totally disproportionate powerplay discussion. this is a bad team.
personally, i think the situation with the terrible powerplay is really for the best. i think it's much better for the team to suck and for real changes to be made than for a terrible 5-on-5 team, terrible possession team, terrible PK team, terrible shootout team to fluke its way to 8th place by scoring powerplay goals and convince old senile rutherford that he likes his group.
Except we're not a terrible possession team. We're pretty average to above average in that regard. Our even strength Corsi is 12th in the league, better than Washington, Montreal, Anaheim, Colorado, Pittsburgh, Philadelphia, Columbus, and Tampa.
Our powerplay Corsi is 18th in the league. Our shorthanded Corsi is 1st in the league.
However, our shorthanded save percentage is 24th in the league, and our powerplay shooting percentage is 28th in the league. Our even strength PDO is 23rd.
So to compare possession numbers to actual puck in net result numbers we are
EV: 12th, 23rd
PP: 18th, 28th
SH: 1st, 24th
To glean anything from these, we'd have to compare the SH%, SV%, PDO numbers to the other situations.
We are 16th in the league in even strength SV% with a mark of .924, but on the penalty kill we sink to 24th and a .867 (16th is .878). So our goalies at even strength are the 16th best in the league, but 24th best on the penalty kill. It's hard to say that means we, as a team, are bad on the penalty kill when we're the best in the league at scoring short handed goals and the best in the league at keeping chances to a reasonable proportion. So this points to one of two things. Either Ward/Khudobin/Peters are just all bad on the penalty kill, or we've been rather unlucky in that regard.
Now the power play. At even strength, we are 12th in CF% and 27th in SH%. On the power play, we are 18th in CF% and 28th in SH%. So we, empirically, have a higher drop off in play from even strength to powerplay when compared to other teams around the league. This points to one of two things. Either we are really really bad at generating quality scoring chances, as evidenced by the drop off from shot attempts to how many of those shot attempts actually go in, or we've been rather unlucky in that regard.
TL;DR: We are a top 15 team in the league at even strength by all possession metrics. Corsi (12), Fenwick (15), and plain old shots on goal (14). However, despite the good possession numbers, we are 23rd in the league in GF%. We are 16th in ES SV%. The only area in which we fall short of being a playoff caliber team is SH%, where we are 27th in the league. We either: need to generate higher quality chances, need to get forwards who are better finishers, or have been rather unlucky when it comes to finishing chances this year.
