Just a short post.
Here are the values for the prospects acquired in the deadline deals as determined by MLB Pipeline, FanGraphs, and 2080 Baseball. An absent value may not mean the player is lowly valued. He may not be considered or simply not enough was known by the site when handing out grades.
Fairly typical through these lists is that FanGraphs tends to grade down players 5 to 10. I have talked to evaluators and they tend to generally like how FanGraphs rankings come together, but all seem to think that the values associated with players are overly conservative.
