But that isn't even true though...
We can actually do the real math here to get a rough idea of the numbers if you want. And look at it in a couple of different ways.
So far this year the Avs have had 190 PP Faceoffs, they've won 75 and lost 115 for a 40% win rate. If you consider 50% to be the true fair outcome rate(Which based on pure simple probability, is accurate), that means they've lost 20 faceoffs more then what they should have under theoretical averages.
If you also then assume every lost faceoff results in 15 seconds of lost PP time... 5:15 of PP time has been wasted by the Avs so far. Or over the course of a full 82 game season using these numbers, you're talking ~12:15 of PP time wasted on lost faceoffs above theoretical average.
Now look at Colorado's PP goals/60. The Avs have spent 171 minutes on the PP this year and have 29 goals scored. That works out to roughly 10.175 Goals every 60 minutes of PP time... or 1 PPG every 5:55 of PP ice time.
That means if the Avs were a 50% faceoff team on the PP instead of 40%, over the course of an entire season, they would score 2.0 extra goals. That's ~1 additional win.
EDIT: Actually, its not even close to 1 additional win. Somebody else already did this math. One extra win in the standings is worth an average of 5.18 goals. So an additional 2 goals over an entire season gets you about 0.4 wins.
In a follow-up to a previous post that predicted winning percentages for teams, this article answers the question, "what is the value of a win?" The results provide insight into how free agency, trades, and general roster construction can predict wins.

Now, you could even go to the complete, unrealistic extreme for the argument. What if Colorado was the first team in league history to win 100% of its faceoffs on the PP. So far on the season, that would be an extra 28.75 Minutes of PP time. Or about 4.65 goals.
Over the course of an entire season, it would be ~76.2 minutes of additional non wasted PP time. Or just under 13 goals.
So if the Avs won 100% of faceoffs on the PP all season long, they'd score an additional ~13 Powerplay Goals. If they actually won the league average rate of 50% instead of the current 40%, they'd score 2 goals more in 82 games. Yep, that certainly seems like a statistic that shows the value of winning a faceoff on the PP.
Basically the argument is that faceoffs matter on the PP to the tune of 0.025 Goals per game.
