ATown certainly posted plenty about how the Phillies' mess with Dom's development at the time. Somehow they managed to both call him up to soon and failed to give him enough of a chance, while also forcing him to change positions. But he's not blameless either (which he's certainly discussed). The really good to great ones still overcome whatever, and now Kingery's the big question mark in the regard.
We should probably appreciate the Francos and Browns and even Hoskins who get as far as they do. There was a time when Michael Taylor seemed a better bet than Dom, and Cozens a better bet than Rhys.
