If we both flip coins 100 times, and you flip 55 heads and I only flip 48 heads, are you better at flipping heads than I am?
If we don't have measurements to determine or assess the validity of our results, stats are meaningless.
Now, if one defenseman is giving up egregious scoring chances seemingly every shift, and another isn't, we don't need stats to verify what we already know. But when we are talking 55% vs 50%, with other variables at play at the same time, we sure as hell do.
