I think Keith should be sent down but that doesn't mean he's a failure. I'm pleasantly surprised by his defense and he absolutely will hit.
This is an evaluation year but that can apply to the journeymen types as well. Why not play Canha, Urshela, Kennedy, etc. now and possibly gain something at the deadline?
Keith or Meadows or even Torkelson going to Toledo doesn't make them busts. It just means they have adjustments to make and it's easier to do that when the games don't count.
