Right, sorry about this being an actual serious answer but my opinion for what it's worth...
Nothing wrong with using stats to back up an argument. But they need to be used sparingly, appropriately, and meaningfully imo.
Anyone who uses acronyms or charts that don't make sense unless you are an analyst is a bad analyst and a bad meff. And anyone who thinks data is anything beyond data without the intervention of human knowledge has no understanding of data.
Analysis 101:
DIKW - Data > Information>Knowledge>Wisdom
Data(in this case stats) stop at stage one of an analysis.
How is that importatnt? Well nearly every argument on here is an analysis. This player is poor/good because of pace/positioning/age/etc
Some people prefer to base it on stats and absolutes, some base it on feeling, some use a mixture, but we all add the next three levels on top of whatever foundation we use in order to create the wisdom we try to share in our posts.
Data tells us Moyes did a great job in the league compared to over a decade of his predecessors...
The other three tells us many fans were angry with him. But some were just bored and some were very happy with him. Some just wanted silvverware or found that the low chance of progress was taking away their footballing enjoyment. Data cannot tell you what's important to an individual. (well it may do in a shopping sense but that's another matter.)
You can argue that sentiment analysis (checking twitter etc for conversations about the club and picking out whether conversation is positive/negative) would provide that response, but if you went to the grounds, or you went online, you get very different responses. Which is correct...
Wisdom says both are correct. Whether you are angry at something or happy with something is opinion, it's not an absolute. Data says that cannot be. Data is absolute, which makes it both a powerful tool when combined with human wisdom but incapable of being flexible enough to cope with many opinons and variations in real world scenarios.
So by all means use them, but only to enhance your results would be my suggestion. But I don't know, I am 99% sure I made 104% of that up.
