Give him the whole year in AAA. Get him 150ish innings. There are plenty of other options to help the ML club. (LeCure, Wood, Maloney, Volquez maybe even Klinker) Why push someone when there isn't any direct need (other than to satisfy quick triggered, impatient fans) to promote him before he is ready. It behooves the Reds to keep him down all year. They will get a couple extra years out of the deal because of it. Get Bray into the bullpen as the LH vs screwing with Chapman's development. Makes so much more sense logically.
