We seem to have trouble developing prospects of any kind though!
Also can't really blame this regime for Williams, Franco, even Crawford, though last year still was very curious with JP. If anything this regime has washed its hands of every player they inherited. And they're not so much developing or not developing them as making internal scouting decisions about them that may or may not be wrong (regarding Williams and Franco, I doubt they are wrong. Regarding Crawford, we'll see).
Honestly when you look at Williams and Franco in the minor leagues, they were never going to be stars. Franco was overhyped because he was all the Phillies had. He never adjusted to become a good major league player after one hot season, which at that point is a different phase of development. And his defense was always suspect. We also hoped Williams might turn into a great everyday corner OF because he was the biggest offensive name in the Hamels deal, but he was maybe third or four on the list of guys we would have really liked from Texas. Bat off the bench always seemed more likely than him producing enough offense to make up for defense. Did the Phillies fail to make those two guys better or is just that who they were always going to be, especially at 25 and older?
The Phillies issue - and the fan and media issue - with non-white players is a longstanding thing of course. But we're kind of randomly selecting here. For every Brown there's been an Asche, for every Franco a Ruf or Joseph. There's also Altherr and Quinn, both probably failed more by their own bodies than the team. And of course there are very few African-American players so they all stand out more (whether failures or successes).
And if we'd had this conversation last July we'd consider Alfaro, Herrera, Hernandez and even Williams himself to be success stories (and Herrera surely was one).
I really wonder about Boras with regards to Williams. He couldn't really force the Phillies to trade Williams but he had to know the combination of Cutch and Harper was going to kill his client's value.
