I just saw in this years data where there is an obvious error as you mentioned. My response is to not throw the baby out with the bath water. Statistics are compiled fairly accurately, and former seasons are almost always 100% correct, as they are no longer changing and have had time to be reviewed and analyzed to ensure correctness. Current season data always has a greater chance to have an error as it is updated routinely and subject to typos.
If your stance is that stats might have errors, so why use them then you needn't post any more stats to back any of your future claims, because they might have errors. The reality is that stats from relaible sources, like the NCAA, while not infallible, are far more likely to be correct than those from random webpages.
