I kind of laugh at the "Jerry has a great personality" comment. I do know that a key member of the Angels Minor League system had 1 interaction with him in 3 years, and that was DiPoto nodding hello while he was on the phone and this person was passing by. Sure, he wasn't a direct report, but why would you not reach out to one of your managers to find out how things are going.
And, to the argument that "if he was so bad, why did he get another job". It's called the Seattle Mariners. I would not use them as the poster child for making great decisions on GM's.
DiPoto reminds me of the Wooden axiom of "don't mistake activity for achievement". He's a volume trader - sometimes he wins, sometimes he loses, but he makes a lot of moves. He's doing the same in Seattle. And, Ric Wilson may be director of scouting, but DiPoto is the guy in charge and sets direction.
By the way, my contact has talked to Eppler multiple times. Does, that mean Eppler will be a better GM? No. But it does show he may be more inclusive in the way he approaches decisions. Servais apparently had a reputation to being abrasive (my contact did not sense that but was told that by a number of people). It will be interesting watching him manage a clubhouse in Seattle.
