Cause it takes time to build up the farm, and then more time to see them mature.
Again, from the Devers call-up in 2017 to the Bello/Casas call-ups, our farm produced Houck, Duran and Dalbec. You don't get sustained winning until that is fixed.
The recent bello/Casas call-ups along with Whitlock's Rule 5 addition and Houck give us a 4 man core. That's not yet on par with what the Astros infusions are doing- both in quality and quantity.
This season and next, we have a much longer list of hopefuls and expected good prospects about to get a chance, plus guys like Crawford, Winckowski, Seabold and Wong still holding some faint hopes.

This may be far from what the Astros have done, but it's big step in the right direction. You don't get there overnight.
