When asked what I expect from a pitcher for the rest of the season, or for future seasons, I use my eye test observations (okay, I'm a bit old school) and I try to provide some thoughts on what to expect and why. What you don't always see is an ongoing process of validating those eye test expectations with analytics. This is the basis of fantasy baseball. It's relatively easy to assign estimated value based on past performance. But, success is predicated on predicting the future, and that objective should always be at the forefront.
