Corbin Burnes, Blake Snell or Max Fried was a significant move for the rotation. Aside from Soto, signing Walker, Adames or Bregman would be significant. I think signing Bregman for 3b would be significant, but that seems to be off the table or it would have been done by now. Trading for Arenado is NOT significant and likely a bad idea. Trading for one of the Mariners starters would be significant.
