Not that I disagree with your premise, but other than altering the initial data, like changing a hit to an error or ignoring some data, how do the numbers get “tweaked”?
The answer is basically in how stats can be weighted in a given calculation. Choices or biases can come into play, intentionally and unintentionally. This can happen comparing two players from the same season, let alone a group of players from various different eras, ie HOF comparisons.
Assume a team loses its first and last games of the season to the same team and misses the playoffs by 1 game. Did that last game have more “implications” than the loss they suffered on opening day, or does that last game only seem to have more riding on it?
That's a great example. Statistically, those games count exactly the same. In reality, the final game where the post season is on the line means infinitely more. The competitive level is simply not comparable (and I think not calculable), even if the lineups and pitching match up happened to be exactly the same as the fist game months earlier. Performance in that latter game is what defines championship players... It's historically been a separator for the HOF. Back to my original point, Jack Morris pitched more of these type games... and not just the final game of a season and probably the greatest WS pitching performance ever... But a greater number of meaningful games in general owing to the fact that he was the No 1 pitcher for three (3) unique World Series championship campaigns... Pitching as the ace down each stretch run. That's something different, in my book, than putting up numbers in otherwise mostly meaningless games with no post season implications. No MLB game is meaningless, mind you... but I use that term just in comparison. Still on the Morris soapbox, I'll repeat that all three teams WON the championship. Winning pennants and WS should mean something! As the ace, a guy is a key team leader... leading the staff and setting the tone in the clubhouse, on the field, in spring training. Either Morris was a great competitive championship leader, or was just lucky to be in the right place at the right time... three times. Numbers on a page just can't reflect the competitive reality. That's why knowledgeable contemporary writers are supposed to do the selecting, not computers.
Assume stats equivalent to ML stats were available for every amateur player for every game they played from the time they started playing kid pitch. Would it then be reasonable to use those stats in the evaluation process?
Not in any sort of college or MLB evaluation, no. But for a kid and parents to "evaluate" how a kid is progressing through levels of competition, how he stacks up to other kids at same level, and for identifying consistent strengths and areas to improve... Sure.
Well, you may look askance at Choo, but I’m a Tribe fan and would gladly swap any outfielder we have to get him back. I watched him play a lot of games and can only say he was a great asset to the Tribe and to the Reds. I think you’ll be very happy with the deal at the end of the year.
Choo is a solid player and fits nicely with the Rangers offnsive needs. He'll be a good addition In the short run. My point is that the team overplayed mightily for him... And this is due in part to other moves that have been made, and not made, putting them in a position where they felt like this is what they had to do.
