Did they say whether Bradish's injury is distal or proximal? Proximal UCL injury can heal without surgery. Distal almost always results in surgery.
I must admit, compare the following 2 rotations:
Burnes, Bradish, Rodriguez, Means, Kremer
and
Burnes, Rodriguez, Kremer, Wells, Irvin.
I'd give the first an A. The second a C+. Ouch.
I'd sign Ryu to a one year prove-it deal. Then I'd hope and pray. If you sign Montgomery or Snell to a 8 year deal, you'll pay outrageous sums for 5 years of non-pitching...
