Dude is still young. Jumped to the pro's right out of college. Has a nice arsenal of pitches. Has a good bat. He is what he is with the potential to get better. Lots of location and speed changing pitchers have had success over the years - Maddux, Glavine, etc. Not saying he'll be those guys. But he has plenty of time.
To me what will be interesting is if some of the farm system pitchers really make strides this year, and how it will affect management's thinking about the future and the payroll.
