What's the point of dragging Heyward through the mud at this point? You're right, this thread has largely been unbearable to read, so don't take it too personally. If Jason Heyward himself was the one to make that post, I would have called him a troll.
Literally not one human on earth thinks the Heyward contract has worked out. It is literally impossible for a statistician to justify its merits emprically, unless they were to arbitrarily assign an enormous value to his leadership. Stat nerds tend to not like the unquantifiable though (to our fault, IMO).
I studied operations research and consider myself a well-trained statistician. Its my education that's taught me that perfect decision making (and even perfect decision making processes) are simply unattainable. If we knew how to perfectly model risk, the fields of finance and statistics would cease to matter. So when you find yourself turned off by the smarm from some of our resident statisticians, recognize that half the time my eyes are rolling to the back of my head just as much yours are I'm sure.
With that said, I don't understand how you can both acknowledge the obviousness that Acuna needs to be sent down, yet reject the discussion of why he needs to be sent down. Of course its not a given he's going to become an elite player that demands $30 million dollar salary. But trying to understand the potential cost of those extra few weeks of seasoning is absolutely relevant to intelligent baseball discussion and if this bothers you then I think you should avoid participating because its, at worst, inoffensive, and, at best, thought provoking.
