Hoffman isn't being sent down as punishment for a bad start. I would look at it more like a DL stint in which the Rockies can pitch him if they want to or rest him if they want to, whereas they don't have that luxury if he's on the 25-man roster.

Ottavino is definitely the weakest link in the bullpen right now. I'm not a fan of Oberg, but I guess I would even prefer to see him get the ball than Otto.
