They don't have 5 Coles, but if they can't even keep a spot open for him right now, they're not going to clog up the rotation any more. They could also use an elite bat. Probably more.
No one said Don Cooper is "infallible."
However, there is a long history of veteran pitchers and hitters going from the AL to the NL and realizing significant improvement. Facing pitchers instead of designated hitters tends to help pitchers perform better, and getting pinch hit or double-switched out of a game in the later innings while your own team is hitting often forestalls a late-inning meltdown.
