Let’s get this out of the way first: Major League Baseball is not going to implement a salary floor and a salary cap anytime soon. If you would therefore like to not think about this anymore, close this tab, and go elsewhere on the internet, you are free to do so. As to why it’s not going to happen, we can turn to Jeff Passan (and his slightly off Elder Millennial book references), who reports that it’s simply not part of the negotiations or point of emphasis for either side.
0%. Saying cap to the union is like saying Voldemort at Hogwarts.
