re: Ian Desmond of the Colorado Rockies opts out of 2021 MLB Season

There is only so much MLB can do, they have more AA participation in the youth level and high school but not in the majors. Mainly because those kids that talented are also talented in other sports which is where they end up devoting all of their time.
Look at LSU and how many kids play both sports, but notice they all play baseball less because football is priority #1.
