1. It is debatable how much of a "top prospect" Anderson Espinoza is. He had a really bad second half of the year. I doubt he is even still a top 25, let alone moving up into the top 10.The only issue with Dombrowski is very similar to that of Belichick in the draft - he wants Tavon Wilson, he blows a second rounder on the player because, well, he's BB and it doesn't matter that Wilson was a 6th rounder at best to everyone else.
Anderson Espinoza's market value should have been worth more than Pomeranz - but because DD "gets his man", it's almost like price be damned. You make the Sale deal 10 times out of 10 - he's an elite performer. But I don't think a guy who deals a top prospect for a mediocre lefty off a good half season represents anything positive.
2. Even top 10 prospects fail to have impactful major league careers quite often.
3. I bet if you look at top 10 prospects in the South Atlantic League, the hit rate is even lower.
4. Espinoza was traded straight up for Pomeranz; how many times in history has a pitcher in low-A been traded straight up for a current All-Star starting pitcher? Consider your history -- Schilling in AA and Anderson in AAA with major league experience for Boddicker. Now tell me again how much more they should have gotten for Espinoza?
5. Look at the list I made above of all the possible outcomes that could lie ahead of Espinoza. What probability do you put on "Becomes a consistently healthy middle of the rotation or better starter before Bradley and Bogaerts sign as free agents with the Yankees?"
