Fantastic thread on twitter concerning how teams move up assets in the AL, this was done by a Jays fan as personal research, so NL teams are not included.
https://twitter.com/enosarris/status/1029525898184155137This is about the only time you'll hear fantastic tread on twitter in the same sentence. The only team in the AL that pushes prospects faster then the Wsox is the Os.
All the "good" developing teams on general keep their players in the minors for atleast .6 years longer then the wsox. (this is the Rays/A's/Indians/Astros/Yankees); 3 teams i follow the most other then the wsox are the Rays/indians/Astros, i suppose this further tints my view against how the Sox do things.
Astros are the only successful team that pushes their prospects to the majors almost as fast as the Sox. they have also had the luxury of having a lot higher draft picks then the Sox over the last 5 years.
