I think the problem is some are focused on the importance of an individual faceoff versus the importance of faceoffs over the course of a season or series. Yes, a faceoff at a certain point in a game can be important, but overall they're not as important as some people think they are. If something happens like 1% of the time over the course of hundreds of faceoffs, overall it's not that much of a factor. If that 1% chance event is a game tying or winning goal, it's much more important to that individual game.
Also, winning the faceoff is just one part of gaining possession. You can win a bunch of draws but if you then turn the puck over or lose a bunch of puck battles, what does it really matter if you won the faceoff? Conversely you can lose a bunch of draws but if you then create turnovers or win a bunch of puck battles, does it really matter if you lost the faceoff?
