I can't wait until 2039 when every team is emphasizing contact and speed and then we would have former players blaming the lack of a Kyle Schwarber type in the league on analytics
Its called a market inefficiency.
If everyone is doing one thing - then "another thing" is going to have more value.
Teams that are on the forefront of what that is will be successful initially.
Then everyone else will copy that, and that market inefficiency goes away ... until a team find some other market inefficiency, and the sort of "cycle" continues ...
This is true about baseball, and about just about anything else.
