With the penchant for 13 pitchers, it doesn’t leave much room for guys you can’t plug in to various defensive positions. Eight guys have to start, a backup catcher, a Jake Marisnick to play some outfield, and another guy who can give an infielder a day off, and you’ve got one spot left. Do you give up a guy like Kemp? For better or worse (and I happen to think for the better), the Astros value flexibility.
