The ABC of baseball analytics

The other day I found a tweet below and took my pen in my hand to remind myself ABC of baseball.

The difference between third base and shortstop is fewer than 0.150 plays per inning. Some people need to understand this and realize that shortstop is not that special.

If you are involved in any baseball activities, you should notice what's strange about this tweet.
From little league to MLB, shortstop is considered a special position due to its difficulty and workload.
The word workload doesn't just refer to the number of fielding opportunities. Communication with the second baseman, catcher, and pitcher, cutting the throw from the outfielder, changing position while shifting is all the factors included.
Assuming how hard (easy) shortstop by just talking about the number of plays per inning is a simplistic way of thinking.
When analyzing numbers, covering all the things that matter and having multiple perspectives are essential. Still, we shall never forget that we must watch the actual game to keep its sense and fill the gap between numbers and reality.
An extreme example will be telling people who know nothing about baseball that the difference between a batter with a batting average of .250 and .333 is hitting once more in 12 at-bats(1/3-1/4). Hence, the batting average is not a meaningful metric. There's a realistic chance that they might believe that assumption.
In reality, There's a world of difference between the expectation of getting a base hit off Ichiro, and Khris Davis(A man of .247BA)

Looking at the profile of the person who tweeted this out, baseball analytics is his primary job, and even he makes a simple mistake like this. We all should be aware not to be tricked by the numbers.
