Nah. It might lack superstar players but it's going to be an assembly line of competent major league position players and pitchers that are regular starters. That's valuable on club control. Allows you to pay your superstars if you extend them at the right time.
I guess if you just want to talk about high end potential star then you can say it's trash. But, with the development team and the pitchers I'm not going to say it isn't possible that they won't turn someone into a star.
The system has been considered "trash" for the last 3 years and it's given you: Chas, Jake, Pena, Diaz, Salazar, Loperfido, Garcia, Brown, Arrighetti, France (huge last year), Blanco- Diaz was a trade but I'd give us the lions share of development- he came over as an A ball dude so I'm going to say he counts in the same way Yordan counts as home grown and developed. That group collectively makes about 10M and that's going to produce something like 20 War this year.
Guys I think can do similar coming up out of this system that's considered trash:
Dezenzo, Whitcomb, Wagner, Leon, Melton, Mathews (I bet you have 3 MLB regulars out of that group and I bet you have 2 fringe guys- who knows which is which)
PItching- Ullola- potential ace- potential bust- I like him and I'm betting on him and our development staff. Bloss, Blubaugh, Tredwell, Kouba, Gordon- those guys will see time at the big league level and so will some pitchers you've never heard of in our system.
I think Baez has star level talent- I'm dreaming on him- but he could also never make it to the bigs.
The Astros system is very good at developing guys to contribute at the big league level. Dana Brown is a swing big type so I assume he's going to be looking at trying to find some top end talent that's special but more likley to bust. I also really like the kid from Houston Ochoa in the 11th round. He's hitting bombs at A ball as an 18 year old and he throws 95 MPH on the mound so you know he's got the arm that drives everyone around here nuts about Jake and Chas. That's a guy you should be happy every time you add one like him to the system as if you do that every year you only need 1 if 5 of 6 to really hit and you are in good shape.
