When Dipoto took over, the farm system was ranked in the top 10. And then the team ended up doing well 3 years later. It's almost like having a strong system leads to future success.
Eppler inherited exactly one legit prospect (Newcomb), who he used to get his SS of the future, since Dipoto left him with no replacement there, either, because he traded the heir apparent (Segura) for 2 months of Greinke. He sure was exciting though! Trades, trades, trades!

In the top 11 were six first rounders, including Mike Trout. Mike Trout probably skyrocketed the Angels' farm team. Notice not a lot of talent between 2010 - 2012. FA Pujols signed in 2012. A loss of a 1st round pick in 2012. FA Hamilton signed in 2013. A lost of a 1st round pick in 2013. DiPoto's MO is acquiring pitchers. Owner Moreno wants hitters. Guess who wanted the Sluggers? Guess who stopped intervening into baseball operations after his meddling proved to be detrimental than helpful? Owner Moreno. 2014, pitcher Sean Newcombe in the first round. 2015, catcher Taylor Ward in the first round.
It's quite facetious to say Newcombe is the only "legit" prospect left behind. Newcombe is only one of two first round draft picks under DiPoto. Also, Newcombe wasn't the only pitcher that was traded for players. DiPoto brought in and left behind starting pitchers Tyler Skaggs, Nick Tropeano, and Andrew Heaney. I believe INF Fletcher and relief P Middleton were under DiPoto's drafts. Newcombe wasn't the only pitching prospect traded. Eppler continued to trade away pitching prospects and never replenished them. Having first round picks does help improve the talent on the farm.
2018 Top Prospects

7. Maitlan, SS (picked up off of Braves farm team in Dec 2017 due to illegal international signing... great find for Eppler... great luck too!)
8. Suarez, LHP (Int'l, 2014 - DiPoto)
Look at all three first rounders for Eppler on there. Must be nice to have first rounders to prop up the talent in the pool.
Now, DiPoto left Eppler with an above .500 team when he left. He also left Eppler with lots of pitching prospects. Why Eppler couldn't make it work is all up to Eppler. Why Eppler couldn't make it work again in 2017 or 18 still seams like a mystery. So far, DiPoto knows how to construct a team that push for a playoff or finish above .500. Eppler grabs nice names, but the construction of the team has netting him three consecutive sub .500 teams.
When DiPoto took over the Mariners, their farm team sucked to begin with. Yet, they still finished above .500 twice. I just keep hearing excuses for Eppler. I like the big name players Eppler's acquired in Simba, Upton, and Ohtani. I love he stole Maitlan b/c the Braves were caught cheating. But those parts don't make a whole. That's what Eppler's missing.
Anyhow, the team had Aybar at SS. Eppler wanted an upgrade. So Eppler made a trade for Simmons. As for trading for Greinke, he did trade away Segura and more. Problem was owner Moreno intervened. Instead of spending $25 mil on Greinke, Moreno wanted to spend $25 mil on Hamilton AND lose out on a first rounder. If you haven't noticed, DiPoto likes to collect pitchers - not hitters. As a GM, losing first rounders isn't a thing you want to purposely do after trading away a top prospects for a player you traded for unless the owner inserts himself.
There are other options, but you're only choosing ones you want to fit your agenda. I'll re-iterate. I thought Eppler was doing a good job until you compare his productions in records. Then you have to re-think what exactly is going on? I know I did this season.
