Can we maybe ease up a bit on the hyperbole?
Steven Wright's stats through the point of the injury:
3.37 FIP, 4.42 xFIP, 2.41 K/BB, 146.2 IP
3.68 FIP, 4.00 xFIP, 4.81 K/BB, 151.0 IP
3.42 FIP, 3.31 xFIP, 4.42 K/BB, 155.2 IP
The most you can say is that he was the third best pitcher through the date of his injury. If you really want to cling to the first half to maximize your position, well, it still doesn't help.
3.60 FIP, 4.38 xFIP, 2.19 K/BB, 114.0 IP
3.84 FIP, 3.96 xFIP, 4.38 K/BB, 106.0 IP
3.49 FIP, 3.19 xFIP, 5.00 K/BB, 116.1 IP
In the first sample, Porcello is the best pitcher, Wright is third best. In the second sample, Price is the best pitcher, Wright and Porcello balance out pretty well. In neither was he the best pitcher. Your position here, much like the argument that pinch running Wright on August 7th was some kind of monumental blunder, is based entirely on results without considering what's going on beneath the surface.
