...and choked...
Here are regular season numbers for 3 years for 3 pitchers:
A: 97 games, 93 starts, 571.2 innings, 3.89 ERA, 1.258 WHIP, 4.05 FIP. 38-36 W/L.
B: 88 games, 67 starts, 395.1 innings, 4.96 ERA, 1.366 WHIP, 4.64 FIP, 17-26.
C: 96 games, 96 starts, 549.1 innings, 3.87 ERA, 1.314 WHIP, 3.95 FIP, 36-31.
It's fun to get excited about release points and potential improvement, but pitching numbers are almost always unstable in the short run and relatively stable in the long term. You can always go back and find numbers to "explain" why a guy did well in a past season, but it's simply a truism of statistical analysis that if you run enough regressions with enough variables, you'll find one with some correlation to the data. That doesn't necessarily mean squat going forward. Guys have one or two bad years and then occasionally excellent ones. Late-career evolutions like Morton (who people seem to forget was actually good for a couple years in Pittsburgh) are rare.
I'd love to be wrong here, but I'd expect a Sanchez next year nowhere near what he was last year, and probably slightly off pitchers A and C above - who are Roark and Gonzalez, by the way. Sanchez is B.
